Notes on the cars:
- Lola T142 [SL142/22] (John Ravenscroft): See full history: Lola T142 SL142/22.
- McLaren M10A/B [300-08] (Johnty Williamson): See full history: McLaren M10A 300-08.
- Brabham BT21 Quattro (Tony Bradwell): Originally intended for the 1968 hillclimb season for Bryan Brown, this car was built by Chas Beattie on a Brabham BT21 chassis using Tony Marsh's four-wheel drive system and powered by a 4.5-litre Oldsmobile V8 engine. The BT21 chassis could have been a very late production chassis, or a second-hand F3 car. The car was often called a BT21X, in the same way that Brabham used BT30X, BT35X and BT36X to denote hillclimb special orders, but it was definitely not the BT21X F3 car that Tim Schenken drove at the Brands Hatch Boxing Day meeting at the end of 1968. Unused by Bryan Brown and sold to Peter Blankstone (Wolverhampton) for 1969. Raced by Blankstone in hillclimbs in 1969 and 1970, finishing second in two RAC rounds in 1970. Sold to Tony Bradwell for 1971 and used in sprints and hillclimbs for another four seasons. Subsequent history unknown but unverified web sources indicate that it went from Bradwell to M. R. Chadney in 1980, to R. G. Romeril in 1983, to Graham Galliers (Shrewsbury, Shropshire) 1985, then Graham Henson (Poulton Le Fylde, Lancashire) from 1994 to 1997. Both Chadney and Romeril are Channel Island hillclimbers; Galliers and Henson also hillclimbed it. It was offered for auction by H&H in 2006 when it was claimed to be "BT21X-1" with a history starting in 1966 with Tim Schenken. This is presumably the BT21X run by Donald Duncan in Richard and Trisha Pilkington's TOPS Club events between 2003 and 2007. Subsequent history unknown.
- Alexis (Rob Turnbull): Rob Turnbull (Walmley, Warwickshire) ran an "F2" Alexis with Ford twin cam engine in sprints and hillclimbs in 1971, 1972 and 1973. Its previous history remains uncertain but Neil McCrudden has established that the car he currently owns, plated TR2, was Turnbull's car. He understands that it started life as a development F3 Mk9 in 1967, and was converted to F2 Mk10 specification probably in 1967. It is unknown from then until 1971. It went from Turnbull to Andy Turnock for 1974 before disappearing for another 20 years.
- Lola T142 [SL142/22] (Arthur Ravenscroft): See full history: Lola T142 SL142/22.
- Brabham BT18 [F2-44-66] (Ron Hartley): New to Clive Baker near the end of the 1966 season, after Baker had given up on the Stockbridge Racing Cooper T83 in May. Built with a Ford twin cam engine for libre racing and first reported winning a libre race very comfortably at Castle Combe at the end of August. The nearly-new car was sold to Bryan Eccles (Solihull, Warwickshire) for 1967 and fitted with a 3.5-litre Oldsmobile V8 engine for hillclimbing. Eccles won a number of events, including the Shelsley Walsh championship hillclimb in August. To Chris Cox for 1968 and used in libre racing. Then to Tony Charnell for 1969 but not seen. It returned to hillclimbing in 1970 when owned by Richard Thwaites (Dewsbury, West Yorkshire) and then in 1971 with Dave Hartley who also used the Brabham-Buick in sprints. Hartley continued to run the car regularly in the British Sprint Championship until 1975. He took class wins in Longton & District MC's Isle of Man hillclimb in 1977 and 1978. Next seen when advertised by Jim Johnston in January 1988. Subsequent history unknown.
- Brabham BT28  (Paul Squires): To Frank Williams Racing Cars and entered for John Kendall in mostly British F3 in 1969. Retained for 1970 until August when Kendall moved the car to Paul Watson Racing Organisation where it was driven by Richard Scott. To Peter Hull for 1971 who advertised it as a BT28 with BT30 chassis. To Bob Shellard for hillclimbs in 1972, then to Phil Kidsley & Paul Squires who ran it in sprint and hillclimbs until at least 1989, using a Cosworth MAE at first but later with a supercharged 1100cc Ford BDA. Said to be with Tommy Reid in 2006.
