Notes on the cars:
- Brabham BT38 [26?] (Tom Klausler): New for Motul Rondel Racing in May 1972, replacing BT38/11, and raced by Carlos Reutemann. Also raced by Gerry Birrell at Albi, when Reutemann was away racing in the Canadian GP. Reutemann left the Rondel team after the Hockenheim race at the beginning of October, following a disagreement over engines, and the car was raced by Ronnie Peterson in the Brazilian F2 series. Sold by Rondel to Tom Klausler (Palatine, IL) for Formula B in 1973, and won at Trois-Rivières in September. Then advertised by Roy Witz (Arlington Heights, IL) in mid-1974, then sold to John Kowalski (Berea, OH) for Formula Atlantic in 1975. Kowalski advertised it in December 1975 as "ex Klausler", still with its "big valve Hart" engine. Used by Kowalski in early 1976, but he then upgraded to a newer Lola T360. The Brabham is believed to have gone to Dr Mike Orgel (Ladue, MO), who raced a Brabham BT38 in Formula B and then Formula Atlantic in SCCA Midwest Division events from 1977 to 1980. After driving in Regionals in 1977, he won the MidDiv Regional title in 1978, and scored 10 points in Nationals that year. He did not appear in the points table for 1979, but scored one point in 1980 in a Brabham BT38. It would then be the "ex-Peterson" car acquired at some point from Orgel by Bob Willis (St Louis, MO), who also owned the Rondel sister car BT38/14.
- March 73B  (Ron Cohn): New to Ron Cohn (Modena, NY), and run as a two-car team with Bruce MacInnes in 1973, entered by DRC Formula Racing Inc in Players Canadian and SCCA Formula B races, running as #56. Retained for 1974, running in the Players Canadian Formula Atlantic series and in the US GP support race at Watkins Glen in October. To Eric Kerman (Hempstead, NY/Glen Cove, NY) for 1975 and updated with new orange bodywork, entered as #81 or #87, and running as a 75B. Raced by Kerman in SCCA Nationals from 1975 to 1979. Later to Oran Bushey (Huntingdon, NY) and raced until 1982. Subsequent history unknown.
- March 71BM  (Charles T. Gibson): New to US dealer Joe Grimaldi and supplied in red bodywork. New to Mike Rand (Greenwich, CT) in time for the SCCA Runoffs, where he crashed in practice. Raced in Pro FB and SCCA Nationals in 1972. Sold to Charlie Gibson (Poughkeepsie, NY) for 1973, and again raced in Pro FB and in SCCA Nationals. Retained again for 1974, when it was run in the Canadian series in 73B specification. Also raced more rarely in 1975, before Gibson advertised it in early 1976. According to current owner Simon Perkins, it was sold for 1976 to "Eric Schneider who only did a few events and then neglected the car when he went off to college". In 1989, Charlie Gibson reacquired the car and resold it to Chris Smith, who had it refurbished by Derek Matthews at Ark Racing in 1989/1990. After racing it occasionally, Smith sold it to Perkins (North Newington, Oxfordshire) who did a few US Vintage races in 2002 and 2003 before bringing the car back to the UK in 2004. He has since raced it in HSCC and European F2 races.
- Chevron B25 [25-73-14] (Chip Mead): Sold to Geoffrey Freeman (Yellow Springs, OH) of Freeman Racing Enterprises for SCCA Formula B. Run by Bill Kuntz' Fastrack Operations Inc (Dayton, OH), for Daytonian Chip Mead in FB in 1973, starting with the SCCA National at MIS in June 1973, and later including rounds of the Canadian series. Probably retained by Mead in 1974 and used by the Shierson team - who ran Mead in his own B27 - as a spare car. Mead's team-mate James King recalls that the third Shierson car, run only at Waterford Hills for Vince Muzzin, was a B25, though described by the press as a B27 'mule'. Given that the only other American B25 (chassis 73-15) is then in the hands of Paul Henry, this is the only candidate for the B25/27 with twin cam engine advertised by Dave Barringer (San Mateo, CA) in The Wheel in November 1981. A restored B25 rolling chassis with dark red bodywork was offered for sale by Kent Bain's Vintage Racing Services (Stratford, CT) between mid-2003 and 2007. In March 2007, it was advertised from Stratford on race-cars.com, still with dark red B27 bodywork and "B25/73/14" chassis plate. Subsequent history unknown.
- Brabham BT40  (Bill Eagles): New to Bill Eagles (Lasalle, Montréal, Quebec, Canada), and raced in the Players Canadian Formula B series in 1973, entered by Tex-Made Racing, Ville La Salle. Also driven by Allan Lader at Sanair in June. Retained by Eagles for 1974, again entered at #46, and fitted with a Cosworth BDA engine after the opening round. Eagles did not continue in Formula Atlantic after 1974, but in 1975 his car appeared at a race at Bushy Park, Barbados. It was still in Eagles' green/yellow #46 livery but it is not clear who was driving it that day. It was later owned and raced by David Kerr in Jamaica, and then sold by him to Richard Knox (Trinidad). Some time later, Knox sold both his Brabhams to UK dealer Bobby Howlings. The movements of the car are then unknown, but by 2005 it was in Tommy Reid's collection, still with Knox's name on the side.
- March 73B (Joe Grimaldi): In July 1974, David Loring raced a Formula Atlantic March at Mosport Park. Canadian Motorsport Bulletin reported that it was "a nice March 73 owned by Dale Lang and supplied by Joe Grimaldi". At the next race, Seb Barone raced what CMB called "the Grimaldi March that Loring had driven at Mosport". From this, it seems highly likely that this was the same car that Grimaldi had raced at the opening two races of the 1974 Canadian series, at Westwood and Edmonton. Richard Paul recognised the car as the March Grimaldi had raced at Trois-Rivières in September 1973, so we can trace this 73B that far back at least. It may even be the car Lang drove at several other races in 1973, but we cannot yet be clear about that. Presumably the car raced by Grimaldi at Waterford Hills in September 1974, but this is uncertain as Grimaldi had a 74B by this time. In 1975, Grimaldi joined forces with Doug Shierson Racing, and DSR ran an older updated March for Price Cobb. Cobb described this in an interview as a 73B, and Grimaldi, when talking to Kevan McLurg in 2020, said that Cobb got Lang's old car. So this seems to be a 73B starting in September 1973, possibly earlier, and continuing until Cobb's last race in it at Trois-Rivières in August 1975. Subsequent history unknown, but this car was unusual for a "75B" in that it had no left-hand radiator, so may have been the Joe Shepherd 75B in 1976.
- Brabham BT21 [BT21A-4?] (Bob Isnor): Sold new to Lou Sell (Fullerton, CA) and first seen in the Pro Formula B race at War Bonnet in late June where Sell qualified on pole and finished second. Then raced in SCCA Regionals and occasional Nationals in California, and in the pro races at Mont-Tremblant and Lake Tahoe at the end of the season. Sold to Sell's backer Dick Smothers (Woodland Hills, CA) for 1968, although Sell also raced it in one SoPac National early that year. To Fred Opert late 1968 in part-exchange for a new Chevron and from him on to Ken Duclos (Boxboro, MA) for 1969. Duclos believes he returned it to Opert at the end of 1969 when he acquired his new BT29 and it next turns up in 1971 with John Sorbello (Lafayette, MA) who widened the cockpit section into a two-seater and added a Chevron B16 body. However, it is possible that the dates of this are wrong and that Bob Isnor (Newton, MA) raced it as a FB before it went to Sorbello. Later to John Kauffman who thought he had bought a Chevron and then to Joe Maria (White Plains, NY) in the early 1990s. It was restored by David Irwin to BT21A spec and was still with Maria in 2007. To Bob Lima (Meadowbrook, PA) by October 2009 and later repainted in Sell's colours.
- Brabham BT40 (Gilles Léger): Gilles Léger (Lachute, Quebec, Canada) raced a white/blue #72 Brabham BT40 in the 1973 Players Canadian Formula B series, entered by Giles Léger Racing Team. Léger bought a new March 74B for 1974, and the Brabham was next seen at Trois-Rivières in September 1974 when it was entered by Fred Opert Racing for Chris Gleason (Johnstown, PA) to drive. It was now in Formula Atlantic specification. Gleason also drove it at Watkins Glen in October 1974. Subsequent history unknown.
- March 73B  (Bruce MacInnes): New to Bruce MacInnes (Sharon, CT) and raced as part of a two-car team with Ron Cohn. Raced in the Players Canadian FB series and in the SCCA Pro FB races at Road America and Watkins Glen. Retained for 1974, and raced in the Players Canadian series again, and in the US GP support race at Watkins Glen in October. Sold to Joe Ostrowski (Trenton, NJ), and raced in NEDiv SCCA Nationals in 1975 and 1976. Presumably the March he raced in NEDiv in 1977 and 1978. Retained by Ostrowski until early 1982 when it was bought by Seann Burgess (Caledon, Ontario). Burgess won the CASC Ontario Formula Atlantic championship and the BARC Drivers Championship in 1982 as well as appearing in 'pro' events. After two more seasons of Atlantic, he converted the car to Can-Am specification at the end of 1985 and then fitted a McLaren M1B body and a Mazda 13B rotary engine for 1986. This "March RX10-B" was raced through the 1986 season. Burgess kept the Can-Am body after the car was retired from racing and sold the March to Richard Smith (Barrie, Ontario) who raced it in 1989 and 1990, still with the Mazda engine, and fitting 1975 bodywork for 1990. He sold it to Chuck Sieber (McLean, VA) who imported it back to the US in January 1991. He raced it in Solo events in 1991, and maybe in one or two more seasons until selling it back to Seann Burgess. Burgess initially restored it to MacInnes' 1973 livery, but at the request of the Villeneuve Museum traded his 73B bodywork to Marchives for a set of 1975 bodywork, and rebuilt the car to resemble Gilles Villeneuve's Skiroule March 75B. By May 2010, it was on display in the Musée Gilles Villeneuve (Berthierville, Quebec).
- March 71BM  (Reg Scullion): Gordie Dewar was appointed March importer into Canada for 1971 and his first purchase, chassis 71BM-1, went to Delta Racing Developments for Ian Coristine (Montréal, Quebec) to race in the Players FB series. Coristine finished the season fifth in the red #50 March but crashed in practice for the final race, at Circuit Ste-Croix in October. The car went to Reg Scullion (Dollard-des-Ormeaux, Montréal, Quebec) for 1972 and it was entered for him by Kris Harrison's Ecurie Canada, and prepared by Andy Roe and Tom Greatorex. Ecurie Canada had also bought Wilson Southam's engine manufacturing business, acquiring Greatorex with it, and were preparing the engines in Scullion's car. Scullion started the season racing in Nationals in Texas before returning to Canada for the Players season. He ended the Canadian season in ninth place but then returned to the US to finish second in the SCCA Run-Offs. He retained the car for 1973 as a Scullion-Donolo Racing entry, and it was raced by partner Louis "Lou" Donolo (Montréal, Quebec) once or twice. Subsequent history unknown.
- March 73B  (Frank Del Vecchio): New to Frank DelVecchio (Trumbull, CT) and raced in SCCA Formula B and in rounds of the Players (Canadian) Formula B series in 1973, 1974, 1975 and 1976. When Formula B changed in 1975 to accept the BDA engine, Frank continued with a fuel-injected Ford twin cam engine. He recalls that he sold the car to Peter Neumahr, who had raced a 71BM/733 in 1976 and would progress to a new 77B in 1977, but is thought to have raced this 73B briefly in late 1976 and early 1977. Neumahr sold the car to Jack Deaso (New York, NY), who DelVecchio recalls crashing it at Lime Rock first time out. Subsequent history unknown.
- March 722 (Wayne Ricciardi): Wayne Ricciardi (N. Haldon, NJ) raced a #24 March 722 in Pro Formula B in 1972, entered by The Race Shop, the US March importer in which Ricciardi and Joe Grimaldi were partners. Ricciardi retained the car for Pro events in 1973, competing in most Canadian events plus the US GP support race at Watkins Glen. Subsequent history unknown.
- March 73B  (Richard Paul): New to Richard Paul (North Hollywood, CA), and first raced it at the Phoenix SCCA National in February 1973 where it was entered as #48, sponsored by Fire Suppression Inc. Paul crashed heavily at Trois-Rivières in September. Paul retained the car for 1974, when it was usually described as a 74B, but wrapped it around a lamppost in practice for the St Johns Formula Atlantic race in July 1974. The car was rebuilt but may have used an older 722 monocoque. Paul entered it as a 742 in races in early 1975. Subsequent history unknown.
- March 71BM (Ken Huband): Ken Huband (Ottawa, Ontario) raced a #9/#8 red-and-white March 71BM in Canadian Formula B in 1973, with support from Tangent Travel Ltd. When Huband advertised the March, together with his older Brabham BT29, in CMB in September 1973, he said it had five races from new. Sold to Norm Joy (Montréal, Quebec) for 1974, with support from T.G.Yachts of Canada Ltd, but he failed to qualify at the opening race, and then skipped the second round. Then to David Westgate (Sainte-Thérèse, Quebec) for the Grand Prix de Trois-Rivières. Subsequent history unknown.
- Brabham BT35  (Al Justason): New to Brian Robertson (Brockville, Ontario, Canada) and raced by him in the Canadian Formula B series in 1971, entered by Fred Opert Racing. To Al Justason (Toronto, Ontario) for Canadian FB in 1972 and 1973. To Fred Beyer (Ottawa, Ontario) for the Players (Canadian) Formula Atlantic series in 1974 and 1975.
- March 722  (Bruce Jensen): Roy Folland (Montréal, Quebec) raced a blue March 722 in the early rounds of the British Formula Atlantic series in 1972, before taking the car to Canada and running in the Players Canadian Formula B series. Sold for 1973 to Bruce Jensen (Kitchener, Ontario) and raced in the Players Canadian series. Sold to Edmond Villa (Clark, NJ), and raced in a New England Region SCCA Regional at Lime Rock in April 1974. In January 1976, he advertised a 722 in Competition Press & Autoweek from Port St Lucie, FL. Ed sold it to Folis Jones (Chesapeake, VA), who raced a March in SEDiv events in 1976 and 1977. This would be the March 722 with '77 bodywork advertised by Folis Jones in December 1978 and February 1979. Subsequent history unknown.
- Brabham BT35 (Ric Forest): Bryant Cougle, an Ottawa sports team owner, owned a Brabham BT35 to be driven by Scott MacKenzie in the 1973 Canadian FB series, entered by Cougle's Astro Sports. MacKenzie crashed the car, believed to be BT35/18, at its second race and both driver and car were unable to continue the season. Cougle owned a second BT35, and this was raced by Ric Forest as an Astro Sports entry at Mosport Park in July. Bertil Roos then drove it at Debert, then Forest returned to the seat for Gimli, winning the race. Forest also drove it at Mosport Park and Trois-Rivières, and in between these races, it was driven by Dave McMillan in two SCCA Pro FB races at Road America and Watkins Glen. Astro Sports did not return to competition in 1974, and Cougle filed for bankrupcy in January 1975. The subsequent history of the Brabham is unknown.
- Chevron B20 [20.72.05] (Peter Ferguson): Sold via Fred Opert and entered for Brian Robertson (Brockville, Ontario, Canada) in Formula B in 1972. To Ferguson/Wilson Racing Team for 1973 and raced by former Miss Canada pageant finalist Linda Wilson in Canadian Formula B. Due to be driven by Ric Forest at Trois-Rivières in September but teammate Peter Ferguson "wiped out" the sister car on the Saturday so took over Wilson's car for the race. Only one of the B20s was seen in 1974, driven by Ferguson, and it seems likely it was the ex-Wilson car. Advertised by Fred Opert in June 1975, suggesting it had returned to Opert in part exchange for Ferguson's new Chevron B29. Advertised again by Opert in early November 1975. Subsequent history unknown until bought as a rolling chassis by Ed Swart from somebody on the east coast who had been trying to restore it. It was black at that stage, and Ed repainted it to orange, the Dutch racing colours, and fitted a BDA engine as he completed the restoration. Raced by Swart from 1989 to February 1993, winning VARA's historic Formula Atlantic West coast title in 1992. Swart then acquired a Chevron B45, and the B20 was sold to Richard Morrison in Tennessee in February 1996.
- March 71BM (Peter W Nye): Raced by Geoff Freeman (Yellow Springs, OH) in SCCA events in Central Division in 1971 but this 71BM did not appear in Pro events until bought by Peter Nye (Fostoria, OH) for the 1972 season. It may be the "ex-works 712 FB" advertised by 'Forward March' of Yellow Springs in February 1972. Nye crashed the car early in the season but rebuilt it on a new tub supplied by March and raced through 1972 and 1973 in Pro events and in SCCA. After relocating to Texas, Nye scored points in Southwest Division in 1974 and 1975. In 1974, Nye loaned the car to Galen Lyons (Austin, TX) and he raced it in one or two SCCA Nationals before it was sold to the Northwest US where its new owners planned to rebuild it as a sports car.
- March 722 (Jon Milledge): William T. 'Bunny' Ribbs (San Jose, CA) entered a black/white #87 March 722 for Mike Eyerly at Road America SCCA Pro FB race in August 1973, then for Jon Milledge at Trois-Rivières a week later. Both drivers had driven Ribbs' previous Brabham BT29. Ribbs retained the car for 1974, when it was raced by Philip Ribbs and Bill Cooper in SCCA events in California. By the end of 1974, the car was noted to be wearing Falconer bodywork. Subsequent history unknown.
- March 71BM [10?] (Ian Coristine): The talented but cash-strapped Ian Coristine (Montréal, Quebec) had run his own March 71BM in 1971, but for 1972 rented an updated car from Ecurie Canada. The 71BM, probably Wilson Southam's old car, was updated to side-radiator 722 specification by team mechanic Tom Greatorex. Coristine stayed with the team for 1973 but the car was put back to 71BM specification. The team almost ran out of money mid-summer, but were rescued by a sponsorship deal with Schweppes. The 71BM was then sold to Mauro Lanaro (Montréal, Quebec) and used in Canadian Formula Atlantic in 1974. Coristine recalls that this car was destroyed in a transporter fire on its way to a race at Debert, but the exact date of this has yet to be determined. Lanaro then bought another 71BM to replace it.
- Brabham BT40 (Craig Hill): Craig Hill (Missassagua, Ontario, Canada) raced a white #2 Brabham BT40 in the Players Canadian Formula B series in 1973, entered by Fother Hill Ltd with sponsorship from Castrol GTX. Retained by Hill for 1974 and fitted with a Cosworth BDA engine for the new Formula Atlantic series, when it ran as #4. Unknown in 1975. It was bought from Opert Racing's Brian Robertson by Howard Kelly (Kingston, Ontario), and raced at the IMSA Formula Atlantic race at Road Atlanta in April 1976, then at a couple of later Players rounds in Canada. Kelly traded it to Jerry Jolly (Denver, CO) for a Lola T322/4 Formula Super Vee. Owners after Jolly are believed to have been George Gettel (Denver, CO) - so it would be the Brabham he raced in 1979 - then Sherry M Fagans in 1981, then Jim Christiansen and then Ron Doyle, who had been Fagans' mechanic at one stage. It was then owned by a man named Forrest Grove (Denver, CO) in 1984, and raced by him with a Mazda engine in ASR in 1985 and 1986. Grove won the MiDiv Regional title in ASR in this car in 1986. After Grove's death, it was acquired from his son by John Streeter (Ford Collins, CO) in 2009.
- Chevron B18 [18.71.1] (Paul Wheatley): A new car built for Brian Redman after he wrecked the development B18 while testing in South Africa. Fitted with a 1.8-litre Cosworth FVC engine and raced by Redman in two races in South Africa in January 1971. This car returned to Bolton and became the works entry in F2 for Chris Craft during the 1971 F2 season. It was then sold to Canadian John Powell and rebuilt to Formula B specification. Powell raced it in the Brands Hatch Boxing Day meeting at the end of 1971 and then loaned it to Brian Robertson to race in the two Bogotá FB races in February and March 1972. Raced by Powell (Ottawa, Ontario) in the Canadian FB series in 1972, Sold to Paul Wheatley (Montréal, Quebec) and raced in the Canadian series in 1973. Wheatley appeared on a couple of early-1974 entry lists but the car was not seen again until he advertised it in April 1975.
- Brabham BT38  (John Powell): Brand new for Motul Rondel Racing at Oulton Park at the end of March 1972, and raced there by Tim Schenken, who finished second. For Schenken again at Thruxton a few days later, then for Derek Bell at Nürburgring at the end of April, by Jean Max at Pau, and by Jean-Pierre Beltoise at Crystal Palace and Rouen. Schenken used the car for the rest of the season, winning at Hockenheim in October. Sold to John Powell (Ottawa, Ontario, Canada) for Formula B in 1973. Sold to Bob Schutt (Kirkwood, MO) at Watkins Glen at the end of 1973, and used by him in Mid West Division FB racing. In the early 1980s, Schutt sold the car to Bob Willis (St Louis, MO), who is believed to still own it in 2019.
- Brabham BT40 (Mike Hall): Mike Hall (Twin Lakes, WI) raced a brand new Brabham BT40 at the SCCA Run-Offs, known then as American Road Race of Champions, at Road Atlanta 25 Nov 1972, the first BT40 to race. Hall then raced this car in Formula B and Formula Atlantic in 1973 and 1974. He replaced it with a Lola T360 for 1975 and the Brabham was then raced by John Elder (Rosemount, Minnesota) in SCCA Nationals in 1975, winning his class at Brainerd in July. Hall had modified his car with a wide nose and a higher and fuller tail, and Elder's car showed the same modifications. The car was then advertised, as "ex-Mike Hall" by Prather Racing (Wheeling, IL) in November 1976. Subsequent history unknown.
- Brabham BT38 [15?] (Bill O'Connor): New for Motul Rondel Racing at Hockenheim in mid-April 1972, and raced all season by Bob Wolleck. Raced once by Carlos Reutemann at Enna. Sold to Bill O'Connor (Highland Park, IL) for Formula B for 1973. To Chuck Dietrich (Sandusky, OH) for 1974, then fitted with a Cosworth BDA for 1975, 1976 and 1977. Subsequent history unknown.
- March 722 Falconer (Charles "Chuck" Hansen): Charles Hansen (Tenafly, NJ) raced a yellow #75 March 722 with Falconer bodywork at a few SCCA Northeast Division Nationals and in the Pro races at Sanair and Trois-Rivières in 1973. He ended the season with 13 points in NEDiv. The 722 was then sold to Jim Modrall (Westport, CT), who had been driving Hansen's previous Brabham BT29 for Erv Falk (Westport, CT) in 1973. Modrall raced the March in a New England Region SCCA Regional at Lime Rock in April 1974, finishing second, and was also entered in it by Falk Racing Inc for the Players Canadian Formula Atlantic race at Mosport in July. After Modrall left the team, the car was also used in practice sessions at Lime Rock by Jeff Gay (Norwalk, CT), but he preferred to race his Brabham BT29. Subsequent history unknown.
- Lotus 59 [59-F2/XB-41] (Max Nerrière): New to Craig Hill (Mississauga, Ontario) and run in the Canadian Road Racing Championship and the SCCA Continental Championship for Formula B, entered by Bill Brack Racing Enterprises. Hill ran in a team with Brack's Formula 5000 Lotus 70, with both cars in marching Castrol GTX livery. Unlike the two JRDS cars, which were entered as Lotus 69Bs, Hill's car first raced in Lotus 59 bodywork and was generally billed through the season as the "Castrol GTX Lotus 59". For 1971, the car was sold to Max Nerrière (Toronto, Ontario), who raced it in the Players Canadian Formula B series. Retained by Nerrière for 1972 and for 1973. Subsequent history unknown.
- March 722 (Seb Barone): Sebastiano 'Seb' Barone (Portland, CT) raced a red-and-white #28 March 722 in Formula B in 1972, entered by J.C. Competition Eng.of Southington, CT. He first appeared at the Bogotá races, but was a non-starter. The car was also used by Bobby Brown, fitted with a Cosworth BDA and running as a Formula A in the Lime Rock Grand Prix in September. Barone finished second in NEDiv FB in 1972. He retained the car for SCCA Nationals in 1973, qualifying for the Runoffs. Subsequent history unknown.
- Brabham BT29  (Archie Snider): John Ranson Lewis III, who raced as Randy Lewis (Sunnyvale, CA), had a blue Brabham BT29 for 1970 which was entered as #7. He raced the car through the full Pro season, finishing fourth at Sears Point in June and at Road America in August, end ending the season in eighth place in the championship. He did not compete in SCCA Nationals. The car was sold to Bunny Ribbs (San Jose, CA) for Mike Eyerly to drive in FB in 1971 (#63) and 1972 (#80). Jon Milledge also drove Ribbs car at Brainerd in Sep 1972. Ribbs, father of future Trans-Am star Willy T. Ribbs, advertised the car at the end of 1972. This is presumably the blue #80 Brabham BT29 raced by Lee Midgley at Road America in August 1973 and driven by Archie Snider at Trois-Rivières a week later. Subsequent history unknown.
- March 73B (Roy Folland): Roy Folland (Montréal, Quebec) had a purple #6 March 73B for 1973 but crashed at Trois-Rivières in Sept and after being repaired, the 73B was sold to Ecurie Canada for guest driver Eppie Wietzes to race at the Watkins Glen Pro FB race five weeks later. Then sold to Tim Cooper (Kansas City, MO) who raced the "ex-Ecurie Canada" 73B at a Willow Springs Regional in December 1973. Raced extensively in SCCA racing early in 1974 and then in the Pro F/Atlantic series, prepared by Charlie Williams Racing. Cooper hired a new 75B and ran as part of Doug Shierson Racing in 1975, but retained the 73B and may have used it in SCCA races. He then went to Wilbur Bunce's team for 1976, and the 73B was rebuilt by Bunce to 75B/76B specification. Cooper then bought a new March 77B for 1977. The subsequent history of the 73B/75B is unknown, but it could be the "75B" acquired by Max Sebba in mid-1977.
- Chevron B20 [72-7] (Peter Ferguson): Sold via Fred Opert to Ferguson/Wilson Racing Team for 1973, when it was described as brand new. Raced by Peter Ferguson (Toronto, Ontario) in the Canadian FB series, but then "wiped out" in practice at Trois-Rivières in September. Ferguson then took over the team's second B20, and it is likely that was the car he drove in 1974. According to documentation later submitted to CAMS, his original car was owned by Players from 1974 to 1978, then was in storage from 1978 to 1984. It was owned by Alex Polsinello from 1984, then George McLean in 1991, then Russell Sewell in 2010. It was bought by Martin Bullock (Western Australia) in 2011.
- Brabham BT40  (Bertil Roos): This would have logically been the first car delivered, but how it was used in the early part of the season is unclear. Bob Kime (Hallstead, PA) acquired the car in the summer of 1973 and raced it for the first time at the Bryar National in early September but crashed it. It was rebuilt by Fran Larkin and loaned the Bertil Roos, who used it to win the Columbo Yogurt Formula B race at the US GP meeting, so it is probably the BT40 that Roos had used on the two weekend before Kime's debut, at Mosport Park and Road America. Kime retained the car for 1974, but having found Formula B a bit quick, opted to convert it to Formula C using a 1000cc Cosworth BDA. Kime accumulated 32 points in Northeast Division FC and finishing second at the Runoffs. The car was converted back for the Watkins Glen GP support race in 1974 but Kime failed to qualify, so the car was raced by Peter Moodie. In early 1975, it was bought by Gary Wallace (Hebron, IN), and raced by him in SCCA Formula B until 1979. Wallace then retained it until the spring of 1990, when he sold it to Cameron McArthur (Loveland, CO) who used it in RMVR events in the Colorado area. It went to Terry Allard in 2000 or 2001, then Bill Swope (Albuquerque, NM) in 2004, and then to Phil Franzone (Perth, Australia) in April 2010.
