Notes on the cars:

  1. March 78B [782-14] (Andy Falbo): Eddie Cheever's car at Thruxton 27 Mar 1978 and presumably all season. To Dick Bennetts Racing and converted to Formula Atlantic for Eje Elgh to race in New Zealand in January 1979. Then to Charlie Kirby as a 78B and raced in Atlantic from 1979 to 1981. Offered for sale in On Track in 1981 by Kirby's Transatlantic Racing Services (Norcross, GA). Next seen with Andy Falbo (Detroit, MI) who raced it in US Formula Atlantic in 1983, and again in 1986 and 1988. Retained by Falbo and still owned by him in 2015.
  2. LM Special [March 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. Significantly modified in 1976 as the Lanaro Special with triangular sidepods, a different nose, and with its Cosworth BDA engine laid on its side. This car went through many evolutions, and was still being raced by Lanaro right up to 1995 when it was used in a vintage event. Lanaro 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.
  3. Lola T360 [HU21] (Peter Dragffy): New to South African Robert Joubert to join his converted Lola T350 in a two-car Formula Atlantic team in the 1975 Canadian Players series. The T360 was driven by his teammate Dave Walker, and was brand new at Edmonton. Joubert did not appear at Trois-Rivières at the end of August, and the entry numbers used suggest Walker drove Joubert's T350. The subsequent history of the T360 HU21 is unknown, but it may have been David Westgate's car at Trois-Rivières in 1975, then that of Victor Larose in 1976. In 1983, Peter Dragffy (Montréal, Quebec) raced HU21 in two WCAR races. It was later bought from the Dragffys by John Arnold in 1989, and was inherited by his son Michael Arnold in 2015.
