Notes on the cars:

  1. Frissbee-Lola KR3 [Lola T330 HU2] (Horst Kroll): See full history: Lola T330 HU2.
  2. Lola T300 [HU15] (Joe DeMarco): Invoice date 30 Mar 1972 (sold to 'Haas', colour 'Yellow'). Horst Kroll (Canada) US 1972-1974; driven by Bert Kuehne US 1975 (5 races); Kroll US 1976; damaged in crash at Watkins Glen but rebuilt and converted to Can-Am. Kroll Can-Am 1977; rental car thereafter: e.g. Marcel Talbot Can-Am 1978 (1 race: Trois-Rivieres - 04 Sep 1978), Can-Am 1979 (1 entry in "T300": Road Atlanta - 06 May 1979, entry list only); Mike Freberg 1981; Duff Hubbard 1982; John Macaluso 1983; Walter Lechner 1984; Joe DeMarco 1985 and 1986; John Graham 1986. Rebuilt as "Frissbee KR5" for 1986. Mike Engstrand recalls driving Kroll's T300-based Can-Am car at St Louis and Hallet in 1986; used until 1987 - Chuck Haines (St Louis, MO) 1989 - Don Jensen (US) about 1998: used extensively in vintage racing still in Can-Am specification until 2007 - Andrew Kluver (Sydney, Australia) August 2007.
  3. March 74B/77B [10] (Mauro Lanaro): The early history of this car is unknown, but it may be the car raced by Gilles Léger (Lachute, Quebec) from Mosport Park in July 1974 onwards. By 1980 it was owned by Bob Roy ( Montréal, Quebec, Canada) and was being used in Can-Am. The car later went to Mauro Lanaro (Montréal, Quebec), and was raced by him in Can-Am then CAT races from 1984 to 1987. At some point, Lanaro found the monocoque had bent due to the Can-Am car's downforce, and replaced the tub with that of 74B/12. The tub and associated parts from 74B/10 remained with Lanaro until he sold his remaining stock to David Clubine (Brantford, Ontario) in 2018.
  4. Rondel M1 [201] (Randy Zimmer): The prototype Rondel was used for testing in late 1972, before the first production cars were built. It was taken to Hockenheim 8 April 1973 as team spare, and to Pau as a spare for Tim Schenken, but not raced. Its history is then unknown until 1974, and it appears it has been acquired by Fred Opert to use as a set of spares. After Mike Rand crashed his car, wrecking the monocoque, 201 was supplied to Ron Ignatowski (Milford, CT), who rebuilt Rand's car on 201's tub with a BRM 1-litre engine and used it in SCCA Formula C. In 1980 it was sold to Randy Zimmer (Buffalo, NY) as the basis for his Can-Am car. He raced it with a Volkswagen engine in 1982 and then with a Mazda rotary engine from 1983 to 1986. Zimmer then entered it for Jim Del Russo in the 1987 CAT championship, and raced it a few more times himself in 1989, 1990 and 1994. Then retained for many years until Zimmer sold it to Seann Burgess (Markdale, Ontario) in 2019.
  5. Sabre 001 [McKee Mk18 '1'] (Robert Goulet): New for Dick DeJarld (Joliet, IL) in 1972, and raced in SCCA Formula A events. Appeared at the Michigan Pro F5000 event in 1973 but did not qualify from the heat. Raced by DeJarld until sold to Ed Midgley (Geneva, IL) for 1976, when it was also raced by Jerry Hansen at Blackhawk Farms. To Robert Goulet (Wauwatsoa, WI) for 1977, and raced in SCCA Formula A. Goulet converted the McKee to sports car bodywork for 1979, appearing at Brainerd in July that year in the ASR class. Raced in Can-Am in 1980 and 1981, then renamed the "Sabre 001" for Can-Am again in 1983, and again in 1985. To Bob McKee and raced by Bill Scott in CAT races in 1986 and 1987. Then restored to its original specification for new owner Tom Simpson (Peoria, IL), and used in vintage racing, appearing at the Chicago Historic Races at Road America in 1988. It ran alongside several other McKee cars in historic races at Road America in the early 1990s, and also ran at HSR Mid-Ohio in August 1993. After a 20-year gap, Simpson ran the Mk 18 again in historic events in 2006.
  6. Chevron B51 [51-80-01] (Tod Tuttle): Martin Spetz observed the number 'B51-80-01' on Tuttle's Chevron at Road Atlanta in 1984.
  7. Chevron B24 [24-73-02] (Mike Engstrand): New for 1973 season. Doug Shierson for Peter Gethin: raced in UK 1973 (won Race of Champions) and US 1973. To Roger Bighouse (Eastlake, OH): raced in US 1974 (7 races); US 1975 (4 races + 1 DNS) - Pat McGonegle (Cincinnati, OH): raced in US 1976 (1 race) and Can-Am 1977 (4 races + 1 DNS); probably the car entered by McGonegle as 'Mannix MX-2' in Can-Am 1978; advertised April 1979 - Danny Johnson (Kewanee, IL) 1979: raced in Can-Am 1979 (1 race), Can-Am 1981 (5 races), Can-Am 1982 (6 races) - Brian R Taylor (now Clive, Iowa) for Mike Engstrand (Des Moines, Iowa): raced in Can-Am 1985 (3 races) - Chuck Haines (St Louis, MO) - Anthony Taylor (Blackburn, UK) 2001: due to be rebuilt and raced in FORCE Historic F5000 series (UK) 2001. Then unknown until owned by Greg Thornton in 2011 and raced in UK and New Zealand 2011/12. Badly damaged in a fire at Thornton's garage in June 2012 but completely reconstructed.
  8. Lola T332/Riley [HU33] (Jim Gustafson): See full history: Lola T332 HU33.
  9. Photon JH2 [March 78B-15] (Jeremy Hill): Jeremy Hill's 1984-86 'Photon' was based on a March 78B Formula Atlantic car but fitted with a 2-litre Hart 420R engine, and a Frissbee-inspired body. A later advert for the car on Race-cars.com gives the car as March 78B/15, an ex-Brack car used for a season by Hill in Formula Atlantic before being converted to Can-Am spec.
  10. Osella PA9B/84 [126] (Fabio Mancini): Martin Spetz observed the number 'Osella PA9B/84-126' on Trentini's Osella at Road Atlanta in 1984. As Mancini's car was also entered by Fiorano Sports Cars of Houston, as Trentini's had been, it is assumed to be the same car.
  11. Lola T332 [HU45] (John Macaluso): See full history: Lola T332 HU45.
  12. VDS 002 (Don Walker): New for the VDS team in 1982 and raced that season by Al Holbert, but exactly when he used VDS-001 and when he used VDS-002 is still uncertain. Acquired by Norwood-Walker Racing for 1983, together with the brand new VDS-003, but VDS-003 was destroyed at its first race. VDS-002 was driven by Michael Roe in 1983. The team was renamed Dallas Motorsports Inc for 1984 and VDS-002 was modified to side-radiator form for 1984, joined later by a new car VDS-004 in normal front-radiator form. Roe dominated the season, winning seven races. VDS-002 reappeared once more at Mosport Park at the start of 1985 when Dallas Motorsports boss Don Walker crashed it heavily in practice. The car remained dismantled for some time while Jack Smith repaired the monocoque. Dallas Motorsports cars and equipment were sold to Frank D'Aquanno (Monterey, CA) in 1987, and in 1989 VDS-002 was restored and sold to Jimmy Landrum (Dallas, TX). In August 2014, Craig McCormick reported that this car was "in a private collection in the Dallas, TX area, completely restored".
  13. Cicale-March 77B (David Locke): Rick Koehler (Milwaukee, WI) raced an Excalibur EE2B in Formula Atlantic in 1978, with sponsorship from Brooks Stevens. The car was essentially a March 77B and was described as ex-Shierson and ex-Brack in adverts in late 1978 and 1979. It was leased to Joe Castellano for the Long Beach race in April 1979, and then sat unused until August 1980 when it was sold to David Locke (Cambridge City, IN). Locke fitted the car with 79B bodywork and Bobsy fenders so that it could be used in Can-Am racing, using an 1850cc Hart BDA engine and Hewland FT200 gearbox. In October 1981, Locke ordered a Kevlar Cicale body for the car, and used it in this form in 1982 and 1983, but without success. He acquired a Hart 420R engine from Jim Trueman for 1984 and raced the car in Can-Am and then CAT until 1987. Chris Townsend advises that it was sold to Lee Johnson in Colorado in April 1988, and was still with Johnson in 2012.
  14. Frissbee GR3 [Lola T330 HU19] (Gerre Payvis): See full history: Lola T330 HU19.
  15. Osella PA9 [110] (Tony LaRosa): Jacques Villeneuve Sr drove an Osella PA9-BMW sports car during the 1982 Can-Am season. This car had began life as a PA8, chassis 091, for Gimax in 1980 and had been converted to PA9 specification and renumbered 110 for Villeneuve's Can-Am run. The car reappeared briefly for Scott Goodyear to drive in 1983.
