Notes on the cars:
- March 75B  (Vittorio Brambilla): A black March 75B sold to Doug Shierson Racing for Jon Woodner in the Canadian series. Raced by Woodner, Marty Loft, Richard Melville and Vittorio Brambilla in 1975 as a Shierson entry.
- March 75B [5?] (Bertil Roos): A yellow March 75B invoiced by March to Ecurie Canada. Based on the colour, the yellow #22 car raced by Bertil Roos in the opening round of the British Formula Atlantic in mid-April, and then the #40 car raced by him in the Player Canadian Formula Atlantic series from late-May onwards, sponsored by Schweppes and Castrol. Subsequent history unknown.
- Chevron B27 [27-74-02] (Tom Bagley): Chevron build record says sold via Fred Opert to Freeman Racing (Yellow Springs, OH). However, either never delivered or bought back by Opert in 1974 and used by Jean-Pierre Jaussaud at Trois Rivieres and Richard Melville at Watkins Glen. Advertised by Opert in April 1975 as "ex-Jaussaud", "only two races". Retained by the Opert team for 1975, and used twice by Tom Bagley at Halifax and Trois Rivieres, where his car is described as "ex Jaussaud". Believed to be Michael Landrum's B27 at Road Atlanta in April 1976 in the IMSA series. Then advertised by Pierre Phillips Autoweek 31 July 76 p28 'ex Bagley'. Subsequently to Frank Scott (Racine, WI) for sale AW 9 Oct 1976 p27 B27 'ex Jaussaud, 8 races from new' and 31 Mar 1978 p39. Sold to Richard Ellingson and used in Mid West SCCA until 1980. Then to an autocrosser and subsequently to Paul Berg (Chippewa Falls, WI), who won the MCSCC F/Atlantic series in 1982 with the car. Owned by Bob Dupré (Glenview IL) 1985 and said to have been written off at Road America that year.
- Chevron B29 [29-75-09?] (Peter Ferguson): New to Peter Ferguson (Toronto, Ontario), to be used in the Canadian Players Formula Atlantic series, entered by Ferguson Canada Racing as #76 with Samsonite sponsorship. The Samsonite deal was not renwed, so Ferguson did not race the car in 1976. He returned for the opening race of the 1977 season, at Mosport Park with Gingerbread Displays livery and finished a highly impressive sixth, but did not reappear. The car was sold to Colin Hine, then to Paul Swinwood, for whom Nigel Mortimer sold it to Dr Warren Eads (Rolling Valley Hills, CA). It next passed to collector Art Valdez (Torrance, CA), and remained in Valdez' collection for many years, until sold to a UK consortium in 2017. Sold to new owner early 2018. Sold to further owner (Kent) late 2018.
- March 75B [74B-3?] (Tom Pumpelly): New to Ecurie Canada, and raced by Gilles Villeneuve (Berthierville, Quebec, Canad) in the Players Canadian Formula Atlantic series with Schweppes sponsorship. Villeneuve was the newly-crowned world snowmobile champion, but had also raced with success in Formula Ford. For the first two races of the season, this car had standard 74B bodywork and a front radiator, but by Gimli on 16 June, he had a new car in the latest specification, and the older 74B was inherited by Chuck Hansen, whose name was on the side of it at Gimli and who then raced at Sanair as an Ecurie Canada entry in mid-July. It then appears to passed into the possession of March importer Joe Grimaldi, and was raced as a Race Shop entry by Dale Lang at Road America in late August. It was then updated to the latest F2 specification for George Follmer to drive as an Ecurie Canada entry at Trois-Rivières when it was described as a second Schweppes March 74B originally meant for Hans Stuck. Raced by Bertil Roos at Watkins Glen in October, then hired by Grimaldi to Eric Kerman for the SCCA Runoffs. Sold by Grimaldi to Tom Pumpelly and run for him by Cavanaugh Racing at the opening two races of 1975, but he failed to start either race. Then thought to have gone with Pumpelly to Doug Shierson Racing but exactly how it was used later that season remains unclear. As he advertised the car in January 1976 as a "74-75B", "ex-Follmer/Roos", the strong impression is that the 75B provided for him by Doug Shierson was actually his 74B updated to the latest specification. Subsequent history unknown.
- March 75B (Price Cobb): Price Cobb (Dallas, TX), a 20-year-old Formula Ford graduate, raced a March 75B for Doug Shierson Racing in Formula Atlantic in 1975, although there is some suspicion that he started the season in a 74B. He stayed with Doug Shierson Racing for 1976, racing a 76B, and it is likely that his 75B remained with Shierson to be sold.
- March 75B (Gilles Villeneuve): Gilles Villeneuve (Lasalle, Montréal, Quebec) ran a March 75B in the Players Canadian Formula Atlantic series in 1975, with some support from Ecurie Canada. He was sponsored by Skiroule Snowmobiles, the Quebec company founded by Rejean Houle and sold to the Coleman Company of Wichita, Kansas in 1972. Skiroule used a signature shade of green, and Villeneuve's 75B was repainted in this colour. Villeneuve won the Gimli race in this car. His 75B was advertised in March 1976 by Doug Shierson, who had presumably taken it in part exchange on Villeneuve's new 76B. Subsequent history unknown.
- March 73B (Frank Del Vecchio): New to Frank Del Vecchio (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 the series move to accept the BDA engine, Frank continued with a fuel-injected Ford twin cam engine. He recalls that he sold the car to Jack Deaso and to Peter Neumar. Neumahr (White Plains, NY) ran it in SCCA Nationals and at the Runoffs in 1977. Subsequent history unknown.
- March 73B  (James King): New to James King (East St Louis, IL) and used in Central Division SCCA Formula B, one round of the Players Canadian series, and the Watkins Glen Pro race in October. Leased to Ric Forest and Fred Phillips in 1974, but King took over the car again for 1975, rebuilt it on a new tub, fitted a March 742 nose and side radiators, and raced it in the Players Canadian series. To Porter Brownlee (Little Rock, AR) 1976, and used in Midwest Division Formula B in 1977. Subsequent history unknown.
- Lola T360 [HU9] (Bobby Rahal): New via North American agent Carl Haas to Bobby Rahal (Glen Ellyn, IL), and raced in 1975 in the Canadian Players Formula Atlantic series and in SCCA Central Division FB. To George Herscher (Charleston, WV) January 1976, replacing a Lola T240, and raced in SCCA Northeast Division and Southeast Division FB. Returned to Carl Haas in May 1977 and sold on to Paul Kelleher (Little Lake, Michigan) in October 1977. To Art Filip (Chicago, IL) in March 1979 and raced in SCCA Central Division, then to Dennis Tobin May 1989, Carl Haas again February 1990, almost immediately to Carl Thompson, and retained until sold to Bobby Rahal February 2000. Retained by Rahal until sold late 2012 via Grand Prix Classics (La Jolla, CA) to Steve Miller (Cape Town, South Africa).
- Lola T360 [HU12] (Tom Klausler): Sold via North American agent Carl Haas to Tom Klausler (Palatine, IL) and run for him by Traylor Engineering in the Canadian Formula Atlantic series in 1975, replacing the earlier car he drove in 1974. Subsequent history unknown.
- Lola T360 [HU10] (Howdy Holmes): New via North American agent Carl Haas to Bill Scott Racing, and run for Howdy Holmes (Ann Arbor, MI) in the 1975 Canadian Players Formula Atlantic series. Also raced by Harry MacDonald at the SCCA Pro race at Brainerd in September 1975. To Joe Colantonio (Glenolden, PA) in 1976, and raced in the Players series. Subsequent history unresolved, but the car was with Mike Brodie in 2009. Acquired from Brodie by Daniel Glanz (Bourton-on-the-Water, Gloucestershire) of Legends Automotive In 2010, and offered for sale with a history that said it had had only two owners from new, and had last been raced by Bill Brodie in 1996. Raced by Glanz in the Formula Atlantic classes of HSCC F2 and Derek Bell Trophy races from 2011 to 2015.
- Lola T360 [HU11] (Elliot Forbes-Robinson): New via North American agent Carl Haas to Bill Scott Racing, and run for Elliot Forbes-Robinson (La Crescenta, CA) in the 1975 Canadian Players Formula Atlantic series with Penthouse sponsorship. Forbes-Robinson won two rounds of the Canadian series in this car. Sold to John Weakley (Nashville, IN) for 1976, who ran as part of the Bill Scott Racing team, but he ran out of finance the car was sold to Ivan Roland (Asheville NC) in 1979. Used by Roland's son Russ Roland in SCCA events until 1982, when it was advertised. It was later sold to someone in update New York, so may be the Walter Nelson car.
- March 712M [71BM-15] (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.
- March 75B [10?] (Craig Hill): A white March 75B invoiced by March to Ecurie Canada. Based on the colour, the white #4 car of Craig Hill in the Player Canadian Formula Atlantic series in 1975, sponsored by Gabriel Special. Subsequent history unknown.
- March 75B [6?] (Chip Mead): Chip Mead (Dayton, OH) raced a red #17 March 75B as part of the Doug Shierson Racing team in 1975 with backing from Zonin wines. H. T. Mead Jr, who was 25 years old and worked for his father's investment company, had previously raced for Doug Shierson Racing in 1974 in a Chevron B27.
- Chevron B29 [29-75-16] (Bill Brack): Sold via US agent Fred Opert to multiple Canadian champion Bill Brack (Toronto, Ontario) and raced through 1975 in STP colours. Won at Halifax in August and at Brainerd in September. Sold to Brad Abbott (Messapequa, NY) for 1976 and only raced twice, both times in SCCA events, scoring a win and a third place according to his later advert. As he did not score points in NEDiv FB in 1976, these were presumably regional events. Abbott then bought a new March 77B and the Chevron was sold to John Galson who raced it in SCCA events in 1977 and 1978.
- March 74B (Reg Scullion): Gilles Léger (Lachute, Quebec) raced a March 74B in the second half of the 1974 season, first appearing at Mosport Park in early July. To Reg Scullion (Dollard-des-Ormeaux, Montreal, Quebec) in time for the Trois-Rivières race in September. Also raced by Scullion at Watkins Glen in October, when it was described as being red/white/blue, and at a couple of races in 1975. Subsequent history unknown.
- March 75B (Patrick Depailler): Tim Cooper (Kansas City, MO) raced a yellow #8 March 75B for Doug Shierson Racing in 1975 with backing from Rutledge Oil. Photographs show that this car had all the features of a 75B, so is unlikely to have been his older 73B updated, although this remains a possibility. Cooper moved to Wilbur Bunce Racing for 1976, and the "75B/76B" that Bunce built up for him is likely to have been based on this 75B (but could have been based on Cooper's older 73B). Cooper raced this car in the Players Canadian and IMSA championship in 1976. He appeared at a few races in early 1977 in a March "77B", thought to be this same car further updated. Subsequent history unknown.
- Lola T360 (Jacques Desjardins): Jacques Desjardins (Ste-Thérèse, Quebec, Canada) raced a Lola T360 at Trois-Rivières in August 1975, and at Road Atlanta in April 1976. Desjardins drove in Formula Ford both before and after these races, so the Lola T360 may have been hired. Nothing more known.
- Lola T360 [HU16] (Tom Gloy): Sold via Carl Haas and Pierre Phillips to Tom Gloy (Lafayette, CA), and raced in SCCA Nationals at the start of the 1975, then in the Players Canadian Formula Atlantic series, sponsored by Hanna Industries. Rented by James Heath for a SCCA National at Willow Springs in October 1975. Sold to Phil Threshie (Alamo, CA), and raced in a SCCA National at Sears Point in April, then in three Californian rounds of the 1976 IMSA series. Advertised by Threshie in November 1976. Subsequent history unknown.
- March 75B (Vince Muzzin): Vince Muzzin (Northville, Michigan) drove a red #99 March 75B for Doug Shierson Racing in Formula Atlantic in 1975. Muzzin's main focus in 1975 was Formula Ford, but he retained the 75B for another season of Atlantic in 1976, but without any success. Subsequent history unknown.
- March 712M [71BM-2?] (Mauro Lanaro): New for Bill Gubelmann (Oyster Bay, NY) and used in British Formula Atlantic at the start of the season, winning at Oulton Park 21 March, and then in the SCCA Pro Formula B series. The car was often described as a 712M but it seems more likely that he used the same 712BM all season. Also raced with a BDA in the Formula A race at Lime Rock in Sep and in one round of the Canadian series. Sold via Joe Grimaldi's The Race Shop to Frank Del Vecchio (Trumbull, CT) and used in NEDiv FB and in a couple of rounds of the Pro series. Sold back via Joe Grimaldi at the end of 1972; Frank thinks it went to a Canadian, and it is very likely to have been the car driven by Ken Huband, Norm Joy and David Westgate in 1973 and 1974. Sold to Mauro Lanaro (Montréal, Quebec) to replace the 71BM he lost in a transporter fire in 1974. Fitted with a Cosworth BDA engine and raced as the LM Special until at least 1977. Whether it is the LM Special he raced from 1980 to 1983 is unclear. The car remained with Lanaro for many years and was eventually rebuilt to original 71BM specification about 1999. In late 2018, it was part of a package of cars bought from Lanaro by David Clubine (Brantford, ON), and was sold to a collector in Ontario.
- March 75B [12?] (Marcel Talbot): Doug Shierson Racing had a yellow #9 entry in the early part of the season for Syd Demovsky and Ian Grob, but this car was sold to Cliff Hansen, and renumbered #33. At the next race after Hansen's purchase, DSR had another car entered as #9, firstly for South African Guy Tunmer at Halifax, then for Quebecois Marcel Talbot at Trois-Rivières, and then for Bob Beyea at Brainerd. It is possible that this was the blue ex-Jon Batchelor 75B/7, which returned to DSR after Batchelor's deal with Cavanaugh Racing fell through. A colour photograph of this car would be immensely helpful.
- March 75B (Tim Cooper): Tim Cooper (Kansas City, MO) raced a yellow #8 March 75B for Doug Shierson Racing in 1975 with backing from Rutledge Oil. Photographs show that this car had all the features of a 75B, so is unlikely to have been his older 73B updated, although this remains a possibility. Cooper moved to Wilbur Bunce Racing for 1976, and the "75B/76B" that Bunce built up for him is likely to have been based on this 75B (but could have been based on Cooper's older 73B). Cooper raced this car in the Players Canadian and IMSA championship in 1976. He appeared at a few races in early 1977 in a March "77B", thought to be this same car further updated. Subsequent history unknown.
- March 75B (Cliff Hansen): Syd Demovsky (Chicago, IL) started 1975 in a Doug Shierson Racing March 75B but left the team after two races. This is probably the #9 car hired by DSR to Ian Grob for Mont-Tremblant 06 Jul 1975 but he failed to qualify, after which it was sold to Cliff Hansen (Laguna Beach, CA) who drove it at that race instead of his usual GRD. Retained by Hansen in 1976 as a show car, and then advertised in September 1976. Sold to Mike Downs (El Segundo, CA) early October 1976 when the invoice identified it as 75B-8. To R. J. (Joe) Ordoqui (Boeing, CA) for SCCA racing in 1978. Used by two further owners in west coast SCCA racing in the early 1980s.
- March 75B ["R1"] (Patrick Depailler): A March 75B built up specifically for Patrick Depailler to drive at Trois-Rivières in 1975 as part of the Ecurie Canada team. Depailler took pole, but the engine broke during practice and he borrowed a different car for the race. The 75B was sold after the race to Bob Kolowich (Mountain View, CA), who raced it in SCCA events in 1976. At the end of that season, Kolowich had to give up racing, and the car was stored. He still owned it in 2008, when he took it out of storage and started to restore it.
