Notes on the cars:

  1. March 712M [5] (Mike Beuttler): New to Mike Beuttler, and raced in F2 in 1971 entered by Clarke Mordaunt Racing with Alistair Guthrie. This must be the ex-Beuttler 712M acquired by Hesketh Racing, and raced by James Hunt at the Rothmans 50,000, and then in the remainder of the F2 season. Sold by Hesketh to Ray Mallock, and updated by March to 73B specification for Mallock to race in British Formula Atlantic in 1973. The car was later rebuilt on the 73B tub that had been used as a bodywork buck. To Arthur Collier 1974 for Irish Formula Atlantic, then to Patrick Woods mid-season. Borrowed by Patsy McGarrity for the Boxing Day race at Mondello Park at the end of 1974. The car was later said to have returned to the UK via AW "Monkey" Brown, then moved through the trade to Roger Andreason, who sold it to his friend Charles Richards to be used in Monoposto in 1978. From there, it moved towards historic racing, but leading to some confusion as the car by now had a 73B tub and 73B bodywork. Its life in historic racing requires further confirmation.
  2. March 712M [14] (Dieter Quester): Thanks to Dieter Quester's BMW connections, he was able to acquire BMW engines for a new March 712M in 1971 and was highly successful, winning at Monza in June and taking a further five second places that season. The car was sold to Freddy Link and became a test car for a planned Opel F2 engine. It was next seen when used as the basis of Kurt Bergmann's Kaimann F2 car, equipped with an Apfelbeck-developed 2-litre 16-valve Opel engine. The car was used with some success in Austrian hillclimbs, finishing second at Dobratsch in 1973, driven by Helmut Koinigg, but the engine failed in practice when it appeared for its one F2 race, at Hockenheim in April 1974. Kurt Rieder drove the car at the Salzburgring F2 race in June 1974, but failed to qualify. The car was sold by Bergmann to Fritz Enn, who fitted a Ford engine and sold it to somebody in Köln (Cologne). Subsequent history unknown.
  3. Brabham BT36 [7] (Carlos Ruesch): New to Automovil Club Argentina (ACA) for Carlos Ruesch to race in F2 in 1971. The car was reported to have been gone to a racing school in Argentina in 1972, but in 1974, the two ACA BT36s were reported to have been driven in local racing by Esteban Fernandino and Pablo Brea. In 2008, BT36-7 was on display in the Museo Juan Manuel Fangio in Balcarce, Argentina.
  4. March 712M [18] (Vittorio Brambilla): New to Ernesto "Tino" Brambilla, and run for him by Scuderia Ala d'Oro in F2 in 1971. Retained for 1972, when it was first fitetd with a Ferrari Dino V6 engine, and later with 1800cc Novamotor BDAs. Retained again for 1973, when it was in Beta livery and fitted with a Schnitzer BMW engine. Subsequent history unknown.
  5. Brabham BT36 [11] (Silvio Moser): New in July 1971 to Silvio Moser to replace his BT30. According to Moser's former mechanic, the car was "probably" sold to Hans Obrist at the ends of 1971 or early 1972 so would be the BT36 used by Hans Obrist (Schinznach, Switzerland) in Swiss national events in 1972. Last known when run by Obrist at the Lorentzweiler hillclimb in Luxembourg in April 1973. Then unknown from 1973 to 1977 but likely to be one of the as-yet unidentified Brabhams running in European hillclimbs. This is probably the car run in French hillclimbs by Michel Salvi (Malbuisson, France, very close to the Swiss border) in 1977, when it still had its 1600cc Cosworth FVA engine. Sold by Salvi in 1978 to Jacky Dalloz (Champagnole, France, not far from Malbuisson) and again used in French hillclimbs. Dalloz is believed to have crashed the Brabham some time around 1980, damaging the front of the car. The next owners were J Plante (Carcassonne, France, in the south of the country), then Alain Filhol (France) 1988 who had it restored by Simon Hadfield. Then to Ermanno Ronchi (Italy) 1992. It failed to sell at a Brooks auction in 2000 and next emerged with Andy Newall (UK) in 2003, having been rebuilt with a new Sid Hoole chassis, the original being retained. Sold to James Murray 2003 and rebuilt with the original chassis in 2006, the new chassis then being sold to Cornwall for a rebuild of a BT35. The BT36 was sold to Josef 'Sepp' Mayer (Heitersheim, Germany) 2008. To Luciano Arnold (Zurich, Switzerland) 2011.
  6. March 712M [15] (John Cannon): John Cannon generally ran his March 712M in Formula 2 but took it to the US in September for the Lime Rock Formula 5000 race fitted with an FVC (MN 3 Feb 1972 p18). In 1972, the car was converted to Formula B specification with a Hart twin cam and raced by Warren G. Ogden III (North Andover, MA) in SCCA events. He advertised the car in Feb 1973 but it may have been the basis of the March 73B that he drove at Virginia International Raceway on 8 Apr 1973.
  7. March 712M [19] (Giovanni Salvati): New to Sandro Angeleri's Ala d'Oro team, and raced by Giovanni Salvati and Gian-Luigi Picchi in F2 in 1971. Taken out to the Torneio Brasiliero at the end of 1971, and Salvati was driving this car when he crashed and died at Porte Allegre in November. It is assumed that the car was written off, and that surviving components would have been used on the two other Scuderia Ala d'Oro 712Ms, 712M/1 and 712M/18.
  8. Brabham BT36 [6] (Carlos Reutemann): New to Automovil Club Argentina (ACA) for Carlos Reutemann to race in F2 in 1971. The car was reported to have been gone to a racing school in Argentina in 1972, but in 1974, the two ACA BT36s were reported to have been driven in local racing by Esteban Fernandino and Pablo Brea. In 2008, BT36-6 was on display in the Automovil Club Argentino Museum in Argentina.
  9. March 712M [16] (Fredy Link): New to Fredy Link, and run for him by Jolly Club in F2 in 1971. Also used in Formula 3 with a Renault Albert engine. To Peter Korda for 1972, and used in hillclimbs, German and Swiss national events, and occasional F2 races from 1972 to 1974. Subsequent history unknown.
  10. Chevron B18 [18.71.3] (José Dolhem): New to Chevron's European agent Jo Siffert and raced by him in the F2 races at Bogotá in February 1971. Driven by Siffert in some European F2 races later in 1971, but more usually by François Mazet, who finished fourth at Pau but otherwise had a difficult season. Raced by José Dolhem at the final race of the year. It appears the Chevron was returned to Bolton after 1971 and found its way into the hands of Roger Hire, who was also running a Chevron B21 with Peter Hanson. The car was then leased to Willie Green and fitted with a 1.9 Alan Smith Cosworth FVC for the Rothmans 50,000 libre race in August 1972. Then unknown until July 1982, when "chassis no. 3 ex Siffert" was advertised from Manton in Leicestershire. Unknown again until 1989, when Robert Campbell raced his red "ex-Jo Siffert F2 Chevron B18-71/3" in HSCC events. A car with this chassis number was auctioned by H&H in May 2002 but did not sell. Next seen in 2014, when a red B18 was advertised by Lutziger Classic Cars, showing the 1990 HSCC papers and a "71/3" chassis plate.
  11. March 712M [17] (Wilson Fittipaldi): New to Wilson Fittipaldi in May 1971, replacing the Lotus 69 with which he had started the European F2 season. Raced by Fittipaldi for the rest of the season as part of Team Bardahl. Retained for one F2 race in early 1972, then sold to Tate of Leeds (Racing) and converted to Formula Atlantic for Chris Meek to race in the British championship. Loaned to Sonny Rajah for the Brands Hatch Boxing Day race. Retained by Tate of Leeds for Malcolm Wayne in early 1973, then sold to visiting American Allen Karlberg (Seattle, WA) who took it back to the US. Entered by Karlberg for Monique Proulx at Watkins Glen in October 1974 and also taken to Trinidad for Formula Caribbean events where it was sold. By 1978 it was owned by David Kerr but it was "totally destroyed" in a towing incident at the "Love Bird International" meeting at Vernamfield Motorsport Park, Jamaica, in December 1978.
  12. Brabham BT30 [9] (Lionel Noghès): Sold new to Rodney Bloor's Sports Motors (Manchester) Ltd and run for François Mazet in F2 in 1970. Raced also by Gerry Birrell once at the end of the season. Then to Monegasque Lionel Noghès and raced under the Écurie Monaco banner in F2 in 1971. Last mentioned in June 1972 when the gearbox was stolen from the car while it was in storage at Lenham Hurst (Folkestone, Kent). Subsequent history unknown. The Noghès family are closely connected to the ruling family of Monaco and it is possible that the car has remained in the principality as part of The Private Collection of Antique Cars of H.S.H. Prince Rainier III.
  13. Lotus 69 [69/71.5.F2] (Emerson Fittipaldi): New to Team Bardahl for Emerson Fittipaldi to race in F2 in 1971, first appearing at Pau in late April. This car was sometimes reported as "69-F2-71-14", or some such variation, but this appears to have been is frame number, not its chassis number. Emerson won at Jarama, Crystal Palace and Albi that season, and also won two races in the Torneio Brasiliero at the end of the year. This car was rebuilt at the factory and fielded as a works entry for Emerson in 1972, supported by Colin Chapman's Moonraker Power Yachts venture, and with fitted with a Cosworth BDF. Fittipaldi won at Hockenheim, Rouen and Österreichring in 1972, and also won one race at Interlagos in October. Sold to Johnny Blades (Whitley Bay, Northumberland) for 1973, still in its 'Moonraker specification' with Cosworth BDF, and very successful in libre racing. Then to Andy Barton (Newcastle upon Tyne) late 1973, and raced in libre for the next two seasons, latterly with a 1600cc BDA. Then to David Muter (Sedghill) for three more seasons of libre racing. Later via Vincent Hayden (Salisbury) mid-1980s for historic racing, Jim Bennett (Denver, CO) late 1980s, Mike Taradash (Palos Verdes, CA) early 1990s, John Delane (Redondo Beach, CA) and Frank Sytner (Monaco) 2007, to Roger Bevan (High Wycombe) late 2008.
  14. Pygmée MDB16 [MDB16-271] (Patrick Dal Bo): Gérard Gamand, Editor of Autodiva, has identified chassis 271 as the car raced by Jean Lachaud in 1972. In June 1973, Lachaud sold the car to Michel Pignard who raced it through the remainder of 1973 and then through 1974. Its racing history in 1975 is not yet established, but it returned in 1976 in the hands of Daniel Boccard, again using a Cosworth FVC engine. He appeared a few times a year with it in 1976, 1977 and 1978. It again fades from view, but according to Gérard this car was owned by Pascal Malateste in 1982. After three further French owners, it was in a private collection in the south of France in 2010.
  15. Brabham BT36 [1] (Tim Schenken): New to Rondel Racing for Tim Schenken to race in F2 in 1971. Sold to dealer Bobby Howlings, and used by him in libre racing in March 1972. Then sold to Tate of Leeds (Racing) for Malcolm Wayne to race in Formula Atlantic, but leased to Graham Hill to use in the early F2 races at Thruxton and Hockenheim before his BT38 was delivered. Sold back to Howlings in May 1972, then to Arthur Moore for libre, but crashed on his debut. For Moore in libre again in 1973, then unknown for two years before Howlings (yet again) raced it in Shellsport G8 in early 1976, fitted with a Cosworth FVC. To John Tait and used in Shellsport G8 in 1976 and 1977. To Eddy D'Hoe in Belgium in 1978, and hillclimbed with an FVA engine. To Regis Jumez 1980, and used in French hillclimbs. Later via Howlings (!) in 1984 to collector Anthony Mayman, then via John Harper and Ted Walker to Peter Williams in 1989. To Andrew Fellowes 2002, then to Ian Rimmer in 2009.
  16. Brabham BT36 [5] (Peter Westbury): New to F.I.R.S.T. for Peter Westbury to drive in F2 in 1971. Retained by Westbury early 1972 and then sold to Neckel 'Nick' Koob (Bettborn, Luxembourg) for French, Belgian and Luxembourg hill climbs from 1972 to 1974. To Johny Krier (Luxembourg) 1975 for French, Belgian and Luxembourg hillclimbs. Then to Roger Hennebert (Belgium) in 1977, then possibly to Marcel Tarrès in 1978, but its exact race results during this time are unknown. Then via four French owners until bought by John Beasley (Shrewsbury, Shropshire) in 1993. Sold to Abba Kogan 1998, and rebuilt on a new chassis. In 2007, the rebuilt car was sold by RM Auctions (agent Annette Abaci) to Thomas Steinke (Hamburg, Germany). Neither Abaci or Steinke were then aware of the car having a new chassis. The original chassis was later sold via Bonhams in 2008 and its current whereabouts are unknown. Meanwhile, the continuous entity of BT36-5 was raced by Steinke in European Historic F2 in 2008 and 2009 and sold to Francesco Molino (Pescara, Italy) in 2012. Then to Günter Türk (Freiburg, Germany) in 2013.
  17. Brabham BT30 [11] (John Watson): Sold to John Watson (Craigavad, County Down, Northern Ireland) for F2 in 1970, replacing a Lola T100 that Watson had used with great success in Irish libre. Retained for F2 in 1971, during which time it was partly updated to BT36 specification. To Bob Howlings (Congleton, Cheshire) for libre 1972 and fitted with a 1800cc Cosworth FVC mid-season. Sold to Tony Dean (Leeds, West Yorkshire) in August so he would have a car for the Rothmans 50,000. To Phillip Guerola (Bickley, Kent) 1973 and raced in libre until the end of 1976. Advertised ("ex-Watson") as a rolling chassis from an Aylesbury number in January 1978 and bought by Barrie Dutnall (Medway, Kent) in 1979 or 1980 but not used. Advertised by Dutnall as a rolling chassis in June 1981. Said to have been owned by Jon Bradburn, David Rishworth (Leamington, Warwickshire) and Kelvin Lambeth before bought by David McLaughlin in or before 2003. To David Brown (Ashford, Kent) 2003. To Ian Gray (Mansfield, Nottinghamshire) 2004.
  18. Brabham BT36 [3] (Bernd Terbeck): New to Bernd Terbeck (Hiltrup, North Rhine-Westphalia, West Germany) and entered for most F2 races in 1971, but often did not arrive, and only qualified for two races that season: Nürburgring in May, and a non-championship race at Hockenheim in October. Retained for 1972 and entered at Hockenheim in April, still fitted with its 1971 1600cc Cosworth FVA. Clipped by Bert Hawthorne's Tui during practice, triggering the accident in which the Kiwi was killed. The Brabham was heavily damaged but Terbeck was unhurt. The car was returned to England for repairs, and was offered for sale by Kaydon Racing (Cobham, Surrey) in August 1972. Returned to Terbeck who sold it to Heinz Stemmer (Münster, North Rhine-Westphalia, Germany). Later to Karl-Heinz Kühn, and then to Hans Peter 1984. Stephan Jocher bought the car from Peter in 1996, and had it for two or three years. It was next seen when owned by Willy Markwalder in 2003. To Heinz Rolf Wisskirchen 2006.
  19. Brabham BT30 [16] (Jeremy Richardson): New to Tom Wheatcroft and entered for Derek Bell to race in F2 in 1970. To Jeremy Richardson and raced in F2 and libre during 1971. Then to Alex Seldon (Ripley, Surrey) and raced in libre through 1972 and 1973. Advertised by Seldon in February 1974 and next owner unknown but the FVA was removed and the car stored in a dry barn until 1984 when Ted Walker bought it via John Harper. Sold to Lincoln Small in 1986 and used for many years in historic racing.
  20. Lotus 69 [71/69.2.F2] (John Pollock): New to Mick Mooney's Irish Racing Cars for Alan Rollinson to race in F2 in 1971, but only appeared once, at Hockenheim. By June, the car was being driven by John Pollock for Gerry Kinnane's Team Ireland in Irish libre racing. Used very successfully in Formula Ireland and in libre at Ingliston by Pollock in 1972. To Paddy Farrelly (Lucan, Dublin) for Irish libre in 1973. The car was next seen when advertised in Northern Ireland in 1977 having been 'virtually unused last 4 years'. Subsequent history unknown.
  21. Lotus 69 [71/69.3.F2] (Gerry Birrell): New to J&J Stanton for Gerry Birrell to race in F2 in 1971. Hired to José Ferreira for the Torneio Brasiliero at the end of the year. To Brian Small in 1972, and fitted with a Cosworth BDA for Formula Atlantic races late 1972, and a handful of appearances in 1973. To Roy Baker (Ferndown, Dorset) July 1973, but again only seen in a handful of races. To Ken Fildes (Clonskeagh, Dublin) for the new Irish Formula Atlantic series 1974 and 1975. Entered by Fildes for a young local lad Eddie Jordan in 1976. To Mark Birrell (Liverpool) in 1977. Acquired from Nick Overall by Richard Hinton (Albury, Hertfordshire) in early 1978, who started the restoration. Sold in 1985 via Chuck McCarty to Richard Spelberg (Dusseldorf, Germany) and retained hin his collection until his death in the late 1990s. Subsequent history unclear, but this car was advertised by Eric Peterson (Germany) in April 2018.
  22. Lotus 69 [69.F2.3] (Adam Potocki): New to Adam Potocki and raced very slowly in F2 in 1970. Retained for 1971, when he was no faster. Sold to Alain Saïdi and raced in French hillclimbs from 1972 to 1975, retaining its 1600cc Cosworth FVA throughout. Saïdi returned to the Lotus for a few events in 1978. According to Gérard Gamand, the car was later bought at auction by Guy Audibert in the mid-1980s, and restored at Gamand's workshops in Lyon. It was sold to Gérard Cerny, who raced it in histori events from the mid 1990s to early 2000s. Then sold it to Michel Ghio, who raced it in Historic F2 2010-2013.

Motoring News 21 Oct 1971 p10 gives the chassis no of Blanc's 1970 Tecno and mentions that it has also run in F3 form. Also (Motoring News 21 Oct 1971 p1), Clay Regazzoni is in the ex-Jaussuad 712M.
