Notes on the cars:
- Ralt RT1  (John MacDonald): New to John MacDonald (Hong Kong) and raced in Sotheast Asian 1600cc 2-valve category racing in 1975, then in the Formula Atlantic and 1600cc 4-valve category in 1976 and 1977. It was also raced by Vern Schuppan at Macau in 1977. Then to Peter Marshall and raced by him in 1978 and 1979, and still in Marshall's ownership when raced by Sonny Rajah in 1980 and 1981.
- Chevron B29 [29-75-05] (Albert Poon): New to Albert Poon (Hong Kong), and raced in Southeast Asian events in 1975. Raced in Southeast Asian 1600cc 4-valve formula events in 1976, and driven by Kevin Bartlett at the Macau Grand Prix in November 1976. Sold less engine to Chong Boon Seng (Singapore) in December 1976 and raced by him in 1977, 1978 and 1979, It was then retained by him until it was sold to Leif Norberg, a Swede then living in Malaysia, in 1985. Then to Tony Armstrong (Australia) in 1989. To Geoff Weiland (Australia) in 1998, then to Peter Addison (Sydney, NSW), then to John Gale (Sydney, NSW) in 2005. In March 2020, the car was bought from Gale by Peter Brennan (Melbourne, Victoria).
- Brabham BT36 [BT30-14] (Chong Boon Seng): Sold new to Ecurie Ecosse and run for Graham Birrell in F2 in 1970. Also raced once by Peter Gethin and by Richard Attwood later in the season. To Peter Westbury early 1971 and raced in several F2 races (also raced once by Dieter Quester) until the team's BT36 was delivered. Sold to Dunnett's Garage, converted to F/Atlantic specification and entered for Ronnie Mackay in libre and F/Atlantic in 1971 and 1972, run by MRE. To Chong Boon Seng for south east Asian racing in 1973 and used by him until 1976. Then to Del Schloemer and raced by him and by Cherie Schloemer in 1977 and 1978. To Wybe Valkema around 1980 and retained to 1982. Then to Australia and with Brian Wilson by 1988. Wilson sold it to Art Valdez (Torrance, CA) and from Valdez it returned to Australia when he sold it to Bob Ilich (Perth, WA) in 2010.
- March 732 (Harvey Yap): Harvey Yap raced a Team Rothmans March 732 in the three main Malaysian races in 1975 (the Grands Prix of Malaysia, Penang and Selangor). The car was entered as #1 in all three races. Singapore GP historian Eli Solomon reports that it was the upgraded ex-Vern Schuppan March 722. Nothing more known.
- Chevron B20 [72-9] (Steve Millen): New to John S Green in Formula B specification but there is no evidence of this car being delivered before the end of 1972. Green ran it in the Gap Hill Climb in January 1973, but only circuit raced it once, in the Singapore Grand Prix in April 1973. Green died in early 1974, and the Chevron was sold to David Schollum for Steve Millen in South-East Asian races that year. Then shipped to New Zealand and fitted with a 1980cc Cosworth FVC engine for the 1975 Tasman series. Used by Millen in 1600cc form at Batu Tiga and Macau later in 1975. Sold to Ian Grey in 1976 and raced with a Cosworth BDM at Macau in 1976 and 1977. Later sold to Dick Ward (Perth, Australia) and George Stacey about the end of 1979, and then to Harry Hickling (ACT, Australia). Sold to David Innes late 2014.
- March 732 (José "Pocholo" Ramirez): New to Sonny Rajah (Kuala Lumpur, Malaysia) and used in British Formula Atlantic in 1973. In August 1973, it was flown to South East Asia, where it spent the rest of its racing career. However, it is difficult to understand exactly how this car was used, as Rajah also owned a March 712M which was updated to 73B specification, and was also involved with a March 723 which had been converted to the local 1600cc 2-valve formula. At the Selangor Grand Prix at Batu Tiga in early September 1973, it appears that Rajah won using his updated 712M/73B, with the 73B being driven to third place by Percy Chan. Historian Eli Solomon reports that Rajah's 73B was bought by Jan Bussell a couple of weeks before the 1973 Macau GP, so would be the car Bussell drove at that race, through 1974, and in early 1975. In May 1975, Bussell left Malaysian for Zaire, and the 73B was raced by Pocholo Ramirez at two races in 1975. Eli adds that Ramirez' mechanic told him he rebuilt the car for Romeo David in 1978, so this would be the car he entered for the 1978 Malaysia Grand Prix. Subsequent history unresolved.
