Notes on the cars:
- Brabham BT40  (John Macdonald): New to John Macdonald (Hong Kong) and fitted with a Hart twin cam engine for the Southeast Asian 2-valve 1600cc formula. Macdonald won the 1973 Malaysian Grand Prix, the 1973 Macau Grand Prix, the 1974 Selangor Grand Prix, and Malaysian and Penang Grands Prix in 1975. Driven by José "Pocholo" Ramirez, Macdonald's Rothmans Cathay Pacific team mate at Macau at the end of 1975. Next seen with Jason Ho in 1988, then with Neville McKay in 1992. Still owned by McKay (Mona Vale, NSW, Australia) in December 2004.
- Surtees TS15  (Graeme Lawrence): New to Graeme Lawrence and raced in the 2-litre class of the 1973 Tasman Cup, using a 1.9-litre Hart BDA. Then raced in Southeast Asian events, using a Hart Ford twin cam engine. Retained for Southeast Asian 1600cc events in 1974, but Lawrence used his new F5000 Lola T332 in the Tasman series. Retained again for Southeast Asian 1600cc events in 1975. He still had the car in early 1976 when he was musing whether to convert it to Formula Pacific. Later in 1976 the car was sold to Rex Hart and fitted with a Cosworth BDA for Formula Pacific, and raced in New Zealand from 1977 to 1981. Sold to Ken Smith in 1982, and sold by him to John Wigston (Auckland) in 1984.
- Brabham BT30 (Kiyoshi Misaki): At the Japanese Grand Prix on 3 May 1971, Hiroshi Kazato raced a Brabham BT30 fitted with a Mitsubishi Colt R39B 2-litre 4-cylinder engine. The identity of the BT30 has not been determined. Two years later, at the Singapore Grand Prix on 22 Apr 1973, Kiyoshi Misaki raced the "ex-Kazato" Brabham now powered by a Toyota Celica twin-cam engine, and was a regular entry in Southeast Asian events through 1973 and 1974, up to Macau in November 1974. Misaki appeared at Macau in 1975 in what was described as a BT40, but could well be the same car. He then raced a BT36 at events in Japan in 1976 and 1977, and it is again possible that this BT36 was his old BT30. Subsequent history unknown.
- March 73B  (Grant Swartz): In the mid-1970s, Grant Swartz (Berkeley, CA) was an aircraft maintenance specialist working for the Flying Tiger Line air freight company in Hong Kong and Vietnam. In 1973, he acquired a March 73B, presumably the chassis 73B/13 that is shown in March records as going to Hong Kong, and he raced at the Macau Grand Prix in November that year. Unfortunately, he hit a wall and broke his ankle. Undeterred, he returned to the Macau race in the car in 1974 and 1975. It was then sold to Nick Van Nugteren (Singapore), who raced it at Macau in 1977 and 1978. By 1978 it had been updated to March 742 bodywork, and was sponsored by Black & Decker. It was later owned by Chris Farrell in Australia, and raced by him in HSRCA from 1999 to 2001. To Robert Foster by 2002, and raced by Foster in HSRCA events from 2004 to 2017.
- March 722 Falconer [722-40] (Vern Schuppan): New to Australian Vern Schuppan to drive in the British Formula Atlantic championship. Fitted with a BRM Ford twin cam engine, and first seen in practice at Mallory Park in late March, but Schuppan left before the race to catch a flight to the Singapore GP. Schuppan finished second in Singapore, and third in the Malaysian GP a week later. Then returned to the British series, now with a BDA, and won four rounds. The car was then fitted with Falconer bodywork and an Amon-Woods engine rebuilt by Geoff Richardson, and raced in the Rothmans 50,000 and in two late-season F2 races. After a single F2 race in 1973 fitted with a Richardon BDG, the car went to Southeast Asia, winning the Singapore GP with a Ford twin cam fitted, then competed in the JAF Grand Prix at Fuji with the BDG, and back to the 'twink' for Macau. He raced the car in British Formula Atlantic briefly in early 1974, then sent it back to Asia where he won the Macau GP in November, by which time it had been fitted with 732 bodywork and a Lola T360 rear wing. It then became a fixture at Macau up to 1977, being driven by Alan Jones and Derek Daly. Patrick Tambay also raced for Theodore Racing in the Malaysian and Penang Grands Prix in 1977, where it was still in 732 form but was billed as a 752. It reappeared at Macau for Schuppan in 1979, now in 76B bodywork. After one more race in the hands of Roberto Moreno, the car was retained by Yip and placed in the Macau Grand Prix Museum.
- March 73B [722-10] (Dieter Quester): New to David Purley and entered by Lec Refrigeration Racing for him in F2 in 1972. Retained for 1973, but converted to Formula Atlantic, fitted with Falconer bodywork and run in the two British championships, winning the opening race of each championship. At Silverstone in May, Autosport reported that the car was appearing for the first time in 73B bodywork and using narrow track. Photographs of the car at the following race, which Purley won, show that it also had front-facing rollhoop supports, which are usually indicative of the 1973 March monocoque, and a more detailed picture of the car at Silverstone in July shows that the front suspension also indicated it now had a 1973 monocoque. He used the car to the end of the season, winning five races in total. It was then raced by Dieter Quester at Macau at the end of 1973, who was said to have bought the "73B". However, Quester's recollection was that it was rented by Team Harper for him to drive. Subsequent history unknown, but possibly sold in the Far East. The car would probably have been indistinguishable from a 73B by this time.
- March 732 (Jan Bussell): 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 for Team Rothmans at that race, through 1974, and in early 1975. In May 1975, Bussell left Malaysia for Zaire, and Percy Chan was moved from the team's second car to drive the 73B at the Penang and Selangor Grands Prix later in the year. The 73B's subsequent history remains unresolved, but it is thought to have been the car raced by Brian Tyler from 1976 to 1978.
- Brabham BT30  (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.
- Brabham BT40 (Albert Poon): New to Albert Poon (Hong Kong) and fitted with a Hart twin cam engine for the Southeast Asian 2-valve 1600cc formula. Raced by Poon in 1973 and 1974 and then, after Poon acquired a newer Chevron B29, the Brabham was raced by Graeme Lawrence in the Malaysian GP in March 1975 and by Kevin Bartlett in the Macau Grand Prix in November 1975. Then raced by Poon's wife, Diana Poon, from 1976 to 1979. At some point, the Brabham was badly damaged, and its tub has been rebuilt by new owner Neville McKay. Reported to be still owned by McKay but in pieces in 2004.
