The brand new McLaren M4A destined for Chuck Dietrich arrives at Robert Amey's house in June 1967. Copyright Frederick Amey 2014. Used with permission.

New to Robert Amey in June 1967 to be driven by Chuck Dietrich (Sandusky, OH) in Formula B, winning the FB class in six Central Division SCCA Nationals and also finishing firth in the Pro race at Mont-Tremblant. Dietrich bought a pair of new M4Bs for 1968 and his 1967 car was sold to Henry H. Hester (La Jolla, CA). Hester ran it in SCCA Nationals through 1968 and then sold it to Dow J. Byers II (San Diego, CA) who used it through 1969 and into early 1970. Probably the car of Clifton Wells (Lynwood, CA) at Ontario in July 1971 and Riverside in April 1972. Believed to have gone to Chuck Hayes at some point but history then unknown until owned by Ed Donnelly (Los Angeles, CA) in 1987. Then via Jim Miller and Rob Merrel (both now deceased) to Jim Brown (San Diego, CA) in 1991 who commissioned a complete restoration including a new tub built by Marc Bahner. In 2004, Brown sold the car to Brian Andrews (San Francisco, CA) who raced it in CSRG events in 2005 and 2006. Sold by Andrews via Fantasy Junction (Emeryville, CA) to Bill Hodder (Nagambie, Victoria, Australia) in 2011. Retained May 2014.

Driven by: Chuck Dietrich, Harry Hester, Dow "Jack" Byers II and Clifton Wells. First race: Wisconsin State Fair Park (R2), 2 Jul 1967. Total of 31 recorded races.

John Tulloch's McLaren M4A in June 2011. Copyright Jeremy Hall 2013. Used with permission.

An unknown car presumably built late 1967 or early 1968. Based on the order in which cars appeared, this could be the little-known car that Malcolm Payne raced in the UK and then quite possibly went to Anthony Lloyd in California. This car is believed to be the tub that sat at Chuck Willis's CRW Engineering workshop for many years. In the late 1990s, a car with this chassis number was owned by Dr Jerry Miller in California who owned it for about 15 years before selling it to John Tulloch (Naperville IL). Tulloch had the car restored by Graham Collins and it appeared in vintage racing from 2010 onwards. Raced by Tulloch at Road America July 2013.

Graeme Lawrence acquired a F2 specification McLaren M4A after he left the Chequered Flag F2 team which was identified in its logbook application and NZ registration papers as chassis number 'M4A-14', implying it was chassis 200-14. Raced by Lawrence from Pukekohe in November 1968, appearing in the 1969 Tasman series and winning the Singapore and Selangor GPs in April. The car passed to Frank Radisich later in 1969 and was raced by him in the 1970 Tasman series. Then owned by Wayne Murdoch in 1971-72 but not raced. To Neil Heney in August 1972 and raced by Doug Heney in club events in 1973, then to Jon Warring for hillclimbs in 1974 and then to Ross Calgher (Waitara, New Zealand) for national racing from 1975 to 1977. Sold by Calgher to George Begg in March 1977 and he sold it to Andrew Cunningham in 1983. Retained to 1990 and then may have passed to Australian ownership until acquired by Peter Herbert (Auckland, NZ) in 1999. Herbert's restoration was nearing an end in December 2009, but the car was not ready for the NZ Festival of Motor Racing in January 2010. On display at Hampton Downs in January 2016. By October 2021, the car was owned by Poul Christie and was on loan to the Rush Collection (Feilding).

Driven by: Graeme Lawrence, Frank Radisich, Doug Heney and Ross Calgher. First race: Baypark Raceway, 28 Dec 1968. Total of 27 recorded races.

An unknown car presumably built late 1967 or early 1968. Possibly the F3 car run by Chequered Flag for Ian Ashley.

Ecurie Intersport for Jo Schlesser in F2 in 1968 until his death in a F1 race in July. Presumably then the "ex-Schlesser" McLaren M4A raced in French hillclimbs by Jean-Claude Fontès (Bayonne, France) in 1969, by Hughes Hazard in 1970 and by Roger Rivoire in 1972. Then unknown until restored by an unnamed German owner in 1990. Appeared in various auctions between 1997 and 2005, in the midst of which Paul Dudley (and Steve Worrad) raced it in historic racing in 1999 and 2000. Sold at Bonhams & Brooks' Silverstone auction in September 2001 to an unknown owner who restored it in 2004 and then sold it via Bonhams Silverstone auction in July 2005. With Lindsay O'Donnell (Christchurch, NZ) in 2005 and raced for him by Ken Smith at Eastern Creek in December 2006. Still with O'Donnell in 2009. Raced by O'Donnell at Lime Rock in September 2011.

Driven by: Jo Schlesser, Jean-Claude Fontès, Hughes Hazard and Roger Rivoire. First race: Montjuich Park, 31 Mar 1968. Total of 23 recorded races.

This number is given for a Formula 2 car entered by Chequered Flag for Robin Widdows until he crashed it at Crystal Palace in June 1968 and it was replaced by a new car, or at least a new monocoque. The car somehow survived and is said to have raced in UK club racing in the 1970s. Found by Lincoln Small and others in an Essex barn c1990. Raced by Small 1996-97 and then by a further owner before the 1999 Coys Silverstone auction. With Graham Earl in 2000 and sold by him to a Belgian collector in 2002. Restored and repainted in Chequered Flag colours in 2012. Advertised on behalf of the owner by Legends Automotive Ltd (Cheltenham, Gloucestershire) in 2014. Advertised on behalf of the owner by Mike van Thiel's Machines with a Mission (Lanaken, Belgium) in November 2022.

Driven by: Robin Widdows. First race: Montjuich Park, 31 Mar 1968. Total of 6 recorded races.

This number is given for a Formula 2 car entered by Chequered Flag for Graeme Lawrence early in the 1968 season, then Frank Gardner and then Mike Walker. Likely to have been one of the four M4As advertised by Chequered Flag at the end of 1968.

Driven by: Graeme Lawrence, Frank Gardner and Mike Walker. First race: Montjuich Park, 31 Mar 1968. Total of 11 recorded races.

An unknown car presumably built in 1968. Possibly the car built with a Rover-Buick engine for John Bosomworth.

Martin Sellers in his McLaren M4A at Summit Point around 1971. Copyright Martin Sellers 2014. Used with permission.

Sold to Martin Sellers (Columbus, OH) for Formula B in 1968. The sale was arranged by Chuck Dietrich (Sandusky, OH) who had run a M4A in 1967 and was now buying a new car for himself as well. Dietrich and Sellers ran together as a team in 1968. Retained by Sellers for 1969 but he had engine troubles through that season and after that only raced the car rarely. In the 1990s, he brought the car out again for historic racing and ran at Sears Point with the SCCA in 1997. More recently a member of the CSRG. Chassis 200-26 is a very rare 1960s racing car that has only had one owner from new. Still owned by Sellers in March 2014.

Driven by: Martin Sellers. First race: Cumberland Airfield (R3), 12 May 1968. Total of 11 recorded races.

Entered by The Chequered Flag in Formula 3 in 1968 for Ian Ashley. Likely to have been one of the four M4As advertised by Chequered Flag at the end of 1968. Very probably sold to the US for 1969. Subsequent history unknown

Driven by: Ian Ashley. First race: Pau, 21 Apr 1968. Total of 12 recorded races.

Late in 1967, Malcolm Payne (Fakenham, Norfolk) was entered in a McLaren M4A by Vegantune at Brands Hatch 10 Dec 1967. He did not appear and did not actually race the car until Mallory Park in May 1968. Not seen again and Payne bought a brand new Brabham BT23C later in the season. From May to July 1968, Williams had advertised a 'F2' McLaren with Vegantune (i.e. Ford twin cam) engine and it is quite possible that Payne's car went to Williams in a trade for the Brabham BT23C. As this McLaren would have been in Formula B specification, it is likely to be the car sold by Frank Williams to Anthony Lloyd in the US in 1968.

Driven by: Malcolm Payne. First race: Mallory Park, 12 May 1968. Only one recorded race.

John Bosomworth (Ilkley, West Yorkshire) had a McLaren hillclimb special built for 1968 using a McLaren M4A tub and equipped with a Buick engine as used by Rover in the development of their V8. The engine was built by Alan Smith and the car was run out of Bosomworth's Otley Road Garage (Skipton, North Yorkshire). Finished in dark blue with an orange nose, the car was mentioned as early as April 1968 in Ken Hammerton's preview of the 1968 season, and it was on the entry list for the June 1968 Harewood meeting, its engine then given as a 3598cc Oldsmobile.

With an extra six inches of wheelbase but the same track, Bosomworth found "the car was utterly lethal and on a circuit could snap out of control in an instant". It was raced in libre, primarily at Croft, in 1969 and 1970. At a hillclimb at Shibden Park in Halifax in August 1970, John reports that "it had a mind of its own and snapped into a crash". Bosomworth's feet were shattered in the accident and he lay covered in fuel until he could be rescued. The car was very badly damaged and although it was later rebuilt, it did not race again.

The car was sold to Barry Taylor, who John describes as "a sort of wheeler dealer in racing bits for very little money". He later died and the fate of the car was unknown until the early 1990s when John was contacted by the son of the man who had rebuilt it. This would coincide with the author being asked to authenticate "the ex-F1 McLaren M4B" by a father and son team of restorers, The simple application of a tape measure proved that it was the Bosomworth car, despite an attempt to paint it in works colours. The manufacture date of its hillclimb tyres quickly silenced any protests.

The current whereabouts of this car are unknown but it is distinctly possible that another attempt has been made to pass it off as the ex-F1 car. In August 2012, an anonymous claim was made on a forum that the ex-F1 M4B was "a project" in New Zealand.

Driven by: John Bosomworth. First race: Croft, 14 Sep 1969. Total of 8 recorded races.

Ron Attig (El Cajon, CA) had a McLaren Formula B in the early months of the 1969 season. After failing to start at SCCA Regional at Stardust International in February 1969, Attig competed in the Riverside and Laguna Seca Pro FB races in April and May but was not seen again. The SCCA Southern Pacific Division Formula B table for 1969 shows him scoring four points for San Diego Region, but in a Brabham. He would have scored four points for his third place finish at Sears Point in late March, but reports at the time said he was driving the McLaren. Nothing more known.

Driven by: Ron Attig. First race: Sears Point, 30 Mar 1969. Total of 3 recorded races.

Stan Huddlestone raced a McLaren Formula B in the Riverside Pro FB race in April 1969. He was not on the entry list, and was near the back during qualifying. Huddlestone did not appear again in Pro FB but the SCCA Southern Pacific Division Formula B table for 1969 shows him scoring four points for CSCC Region (Cal Club). However, his car is shown in the table as a Brabham, and it maybe that he drove a Brabham at Riverside which was misreported as a McLaren. Nothing more known.

Driven by: Stan Huddleston. First race: Riverside (R1), 20 Apr 1969. Only one recorded race.

Max Callicott (Anaheim, CA) raced a Formula B McLaren M4A in SCCA Nationals in the 1969 season. His 1969 Drivers Licence application lists the Sears Point National in July as his first outing, but he had revealed plans to race the McLaren as early as March. A letter from Callicott dated 1996 that is with the car says that he bought it direct from The Chequered Flag in 1968, and states that it had been a F2 car raced by Ian Ashley and Piers Courage. Neither Ashley nor Courage raced for Flag in F2 but Ashley raced for them in F3 so this may actually be his F3 car. Callicott drove the car again in 1970, then took two seasons out before returned for the 1973 season, having to go through Drivers School with the McLaren in January 1973. He then competed in three rounds of the Canadian FB series and at one of those was said to be driving a March 73B instead of his faithful old McLaren. The March is likely to have been a hire car or a transcription error. Callicott was not seen again and sold the McLaren to Peter Boyd (Anaheim, CA) in 1981. It then went to Richard Wells in 1983 and to Mike Fazzi from 1988 to 1995. It was rebuilt with a new Marc Bahner tub while Fazzi owned it as the rear of the original tub had been cut off. The new tub was modelled on Jim Brown's 1967 car but used the original bulkheads. The rebuilt car was with Tom Crowther in 2000 when Trojan "allocated" it the identity '200-13' on the basis that 200-13 was one of the F3 cars sold to The Chequered Flag. Owned by Tom Lee (Seattle, WA) by 2009. Advertised by Kim Baker's Vintage Race Car Sales (Pittsfield, MA) and sold to an unknown UK owner in 2013.

Driven by: Max Callicott. First race: Sears Point, 20 Jul 1969. Total of 8 recorded races.

Leo Wybrott's McLaren M4A on display in Perth in December 2007. Copyright Matt Dwen 2007. Used with permission.

New Zealand F3 driver Howden Ganley performed some testing for his friend Bruce McLaren on the Can-Am M8A in early 1969, and as part of the deal was able to build up a car for a Formula 2 campaign. The car used a McLaren M4A monocoque but with special bodywork designed to make it a "mini-M7". Money problems and delivery delays meant that Ganley never raced it, focusing instead on a successful F3 season. The McLaren was next seen when advertised by Jim Gleave of MRE (Bourne End, Buckinghamshire) in May 1971 as a "brand new" McLaren 'M4C' built for Ganley. It was sold to Jan Bussell (Kuala Lumpur, Malaysia) in time for the Malaysian GP in early September. The car was then reported to have used second-hand M4B F1 suspension and a new body based on the M7 F1 cars. As well as the designation 'M4C-1', it was also reported to carry the chassis number 'FJB4' for Bussell. It was modified to take a Ford twin cam engine and used by Bussell at the Malaysian GP, the Macau GP in November 1971 and at the March 1972 Singapore GP, during which it was damaged by fire. Its history is then unknown until it was found in Malaysia by RAF engineer Irwin Lindsey and brought back to England where it was sold in June 1984 to McLaren's Leo Wybrott. Wybrott subsequently reported that the car had been built using the original monocoque from M4A/2, crashed at Brands Hatch in August 1967, and he restored the car over some period to the same specification as M4A/2. It was on display in the Donington Museum and at the Midland Museum from 1992 until 2005, when Leo moved to Australia, and the M4A moved to the Fremantle Motor Museum in West Australia. Raced by Leo at Barbagallo Raceway in August 2010 and at the Collie circuit in Western Australia Feb 2014. Owned by Leo until 2016, when it was sold to a UK owner. In June 2019, it was for sale at McLaren Manchester.

Driven by: Jan Bussell. First race: Batu Tiga, 5 Sep 1971. Total of 3 recorded races.

In the mid-to-late 1970s, James Gardner and James Hunt, both club racers from the Preston area of Lancashire, ran a number of single seaters in libre racing. First of these was a McLaren M4B, which Gardner ran in a sprint at Oulton Park in early 1975 and Hunt then raced in minor club libre later in the year. The identity of the McLaren remains unknown.

Driven by: Paul Gardner and James Hunt (II). First race: Oulton Park, 6 Apr 1975. Total of 2 recorded races.
