New to Peter Hull for British F3 and selected European events in 1972, using Vegantune engines and sponsored by The Motor Auctions London and Derby. Its history after 1972 is a puzzle as Hull recalls selling it to Jimmy Fuller but Fuller's car in 1973 was described as being the former Chris O'Brien car. Subsequent history unknown.

Driven by: Peter Hull. First race: Brands Hatch (R1), 19 Mar 1972. Total of 24 recorded races.

Unknown in 1972 but likely to be one of the car raced by Tony Brise, Brian McGuire or Alessandro Guidetti.

New to American Randy Lewis for British and European F3 in 1972 with Novamotor engines and sponsored by Wrangler, but only picked up a few days before the Estoril race in mid-June. Believed to have wrecked at some point in Lewis's European travels and rebuilt on a new monocoque as its AM number indicates a very late chassis. In August 1974 and again in April 1976, Lewis advertised a BT38 with BT40 suspension and Cosworth BDA engine which had not been raced since 1972. This suggests that Lewis had taken his car back to the US and converted it to Formula B but it is also possible that this was a different car. Sold to Tom Smith (Redwood City, CA) in 1977 with a Hart twin cam, then to Greg Loscher (Kensington, CA) who fitted a Cosworth BDA and ran it for some years in FB and then SCCA Formula Atlantic, at least until the end of 1983. He eventually sold the car and it was next seen when advertised online in 2001 as BT38C-17. By 2006 it was owned by Mike Truitt in Colorado but it has not been seen since.

Driven by: Randy Lewis and Gregory Loscher. First race: Estoril (R8), 18 Jun 1972. Total of 14 recorded races.

New to Canadian driver Chris O'Brien and raced in British F3 in 1972 using Holbay engines. To Jimmy Fuller for 1973, again in British F3 and again using Holbay engines. Advertised by Fuller from Sunbury-on-Thames as a "BT38/41" with two rebuilt Novamotor twin-cams, a spare monocoque and bodywork for £2,250 in November 1973. Formula 3 changed to 2000cc for 1974, and the BT38C was sold to David Taylor (Formy, Lancashire, later Merseyside) for Kim Mather to race in British Formula Atlantic in 1974. When the car first appeared, it had a RES BDA engine and still used F3 wheels, Mather recalling that he "just dropped a BDA in it". By the end of May it had a Richardson BDA and wider wheels, but it was still far off the pace of the leading cars, and this turned out to be its last Atlantic race. Taylor also used the car in sprints at Longridge, and Mather won two libre races at Aintree. Taylor advertised the car in September, complete with Richardson BDA, for £2,200 and sold it to Ted Payne (Middleton-in-Teesdale, County Durham). Payne had raced a BT38 earlier in the season with a Vegantune engine, but it appears he had sold that car and had bought Taylor's very similar one with its Richardson engine. Payne continued to race the car in 1975, and entry lists show that it was black with a Richardson engine, and generally entered as a BT38-40. It was advertised by Payne in November 1975 as a BT38/40 with a recently rebuilt Cosworth BDA engine, and with a spare monocoque. It was bought by Andrew Wareing (Kirkham, Fylde, Lancashire), whose recollection is that it came from Joe Applegarth, but Applegarth says he never owned a BT38. Wareing used it in sprints and libre in 1976. He advertised it in September 1976 as a BT38/40 with BDA engine, 10" and 14" wheels and a spare tub, and recalls that it went to a family of hillclimbers, father and sons. This must be John Hart (East Dulwich, London), who after hillclimbing a Brabham BT18 in 1976, transferred its Cosworth FVA engine into a Brabham BT38 for 1977. Hart recalls buying the BT38 in the Isle of Man, but it is quite plausible that the car had acquired an Isle of Man event sticker if Wareing had competed in one of the Longton & DCC events on the island. Hart raced this car in hillclimbs and sprints through 1977, being joined by his son Greg later that season. The pair retained the BT38 for 1978 but Greg wrecked it in a major accident at Shelsley Walsh in August, which he was lucky to escape. The car was briskly rebuilt using a BT40 monocoque acquired from MRD and raced again at Gurston Down just two weeks later. The car was renamed 'Hart JG79' for 1979, fitted with a 1600cc Richardson FVA and raced by Greg and John in 1979 and 1980. Doug Hart recalls that the BT40 was sold to Paul Squires, "who sadly died at a young age and before he finished the car". Subsequent history unknown.

Driven by: Chris O'Brien, Jimmy Fuller, Kim Mather, David Taylor, Ted Payne, Andrew Wareing, John Hart and Greg Hart. First race: Silverstone (R4), 22 Apr 1972. Total of 57 recorded races.

New to Conny Andersson and raced in European F3 in 1972 using Novamotor engines. Retained at the start of 1973, until Andersson's new March 733 arrived. To Mats Byström, and raced in Swedish F3 in 1973. To Rolf Johansson, and raced by him in Swedish F3 in 1974 and 1975.

Driven by: Conny Andersson and Rolf Johansson. First race: Mantorp Park (R2), 4 Jun 1972. Total of 14 recorded races.

New to Vittorio Venturi and raced in Italian F3 and Italian hillclimbs in 1972. The car was reported by Autosprint to have been rebuilt as a F2 for 1973, and it is understood to be the Marlboro-backed car that he used in European hillclimbs that season, while acquiring a new BT40 for Formula 2. Scuderia Nettuno had an intention to run the BT38 in circuit racing, to be shared by Spartaco Dini and Demetrio Martino, but the only appearance of this found so far was an entry for Demetrio Martino at Misano in July 1973. Subsequent history unknown, but in 2012, this car was photographed in Italy on display attached on a wall. It was in Marlboro Nettuno livery which appeared to be original.

Driven by: Vittorio Venturi. First race: Misano (R8), 6 Aug 1972. Total of 3 recorded races.

New to Tony Brise (Dartford, Kent) and raced in British F3 in 1972 using Holbay engines. Crashed in testing after just one race, and rebuilt on a Formula 2 monocoque. Won at Oulton Park in April, and at Brands Hatch in August, before Brise replaced it with a GRD 372. It was noted to be not wearing a chassis plate, but its very early appearance suggests it was BT38C/13. The car was sold to Edgar Richoz in Switzerland in time for the 1973 season, and fitted with an 1000cc engine for the 1000cc class of the Swiss national championship. After just a few races, Richoz retired from racing to take over the family business. It would appear that the car was run for other drivers over the next few seasons, as Chris Townsend's research shows Florian Arlettaz of Orsières driving a 1-litre Brabham BT38 from 1974 to 1976, then Serge Favez, also of Orsières, driving a BT38 in 1977 and later Gaston Zen-Ruffinen with a BT38 in 1981. The BT38C evidently remained with Richoz, as it was offered at auction "from the Richoz Collection" by RM Sothebys in July 2020. At the time of the auction, the car was fitted with a 1000cc "Ford Anglia" engine with single downdraft Weber carburetor, implying an ex-F3 MAE engine. Acquired by Sebastien Mangenot (France) in 2023.

Driven by: Tony Brise, Edgar Richoz and Florian Arlettaz. First race: Mallory Park (R1), 12 Mar 1972. Total of 25 recorded races.

Entered by Jolly Club Milano for Carlo Giorgio to drive at Misano on 6 August 1972. Giorgio appeared once more in the car, at Misano again two weeks later. Nothing more known.

Driven by: Carlo Giorgio. First race: Misano (R8), 6 Aug 1972. Total of 2 recorded races.

Ted Payne (Middleton-in-Teesdale, County Durham) raced a Brabham BT38C in 1974, appearing mainly in libre races at Croft. It was fitted with a 1600cc Vegantune twin cam, presumably its former F3 engine, and entry lists show that the car was orange. In September 1974, Payne advertised the car as a BT38 with its "demon" 1600cc Vegantune twin cam engine for £1,750. Payne bought David Taylor's BDA-engined BT38C in September, and it would appear that the black BT38 that Payne raced at Croft in November 1974 with a Richardson BDA in it was the ex-Taylor car. In June 1976 a BT38-40 was advertised from a Shildon, County Durham address with Vegantune twin cam engine, a five-speed Hewland gearbox, and 9-inch and 10-inch wheels. This must surely be the Brabham BT38 with Vegantune engine bought by John Simpson (Darlington, County Durham). He spent some time replacing the engine with a 1600cc Swindon BDA and fitting a set of Falconer bodywork acquired from dealer Bobby Howlings. Simpson recalls that the car still had the smaller Hewland Mk8/9 gearbox, not the more typical F/Atlantic FT200. He first raced the car in this form at Croft in October 1976, but due to business commitments, only raced it a few times and advertised it in November 1976 as a BT38C "updated to Atlantic spec with Falconer bodywork and Swindon engine" with its original bodywork and side radiator included. He recalls selling it to somebody "south of him", but from Darlington that is pretty much the whole of England.

Driven by: Ted Payne and John Simpson. First race: Croft, 27 May 1974. Total of 8 recorded races.

Bonde Hallenmark raced a Brabham BT38C in Swedish Formula 3 in 1976, 1977 and 1978. As Ulf Svensson's BT38C/14 and Thorbjörn Carlsson's "ex Magee" BT38C/18 can be traced into 1976 or 1977, this is likely to have been the ex-Conny Andersson BT38C/21. Subsequent history unknown.

Driven by: Bonde Hallenmark. First race: Mantorp Park (R1), 18 Apr 1976. Total of 23 recorded races.

Pete Oxley (South Humberside) raced a 1600cc Brabham in a libre race at Oulton Park in March 1977 which he entered as a Brabham BT40. Two weeks later, he was entered at Oulton for another libre, and now the car was described as a Brabham BT38L with 1600cc Swindon engine. This car was bought from him by Stewart Robb (Alloa, Scotland), who remembers it as a BT38, not a BT40. Like John Hart's car that appeared about the same time, photographs show that the car had Falconer bodywork when Robb bought it from Oxley. He raced it as a BT38/40 in Formule Libre at Ingliston in 1978, and when he advertised it at the end of that year, again as a BT38/40, mentioned a 1600cc Swindon BDA engine and Hewland Mk 9 gearbox. Robb sold the car to Noel le Tissier and it was run by his mechanic, Tom Coughlan (Guernsey, Channel Islands) in Guernsey sprints and hillclimbs in 1979 and 1980. Coughlan appeared again with the car at Le Val des Terres in 1981, and then appeared in events at Gurston Down in 1982 and 1983. He was entered in at least one event at Le Val des Terres in 1984. The car was then sold to Andy Sauvarin who raced it in Guernsey using a 1600cc Cosworth BDA engine from 1984 to 1986. Some time around 1987, it was acquired by Kevin Timms (Trowbridge, Wiltshire) and retained by him until February 2012 when it was advertised. It was sold to Nigel Edwards (Cheshire) and rebuilt by Nick Edginton during 2013, emerging in April 2014 in Jagermeister orange. Raced by Edwards at the Oulton Park Gold Cup in August 2014. Bought from Edwards via Damon Milnes at Adam Sykes & Co by John Albiston (Elgin, Scotland) in November 2022. By April 2023 it had been rebuilt with an alloy BDG engine and raced for the first time at Doune.

Driven by: Peter Oxley, Stewart Robb, Tom Coughlan and Andy Sauvarin. First race: Oulton Park, 12 Mar 1977. Total of 14 recorded races.

A car raced by Seb Proctor in Classic F3 entered as #37. David Proctor advises that "This car was originally built around a new tub by Tony Broster for Arian Ramirez but it was sold to Alistair Morrison for 1600F3". Morrison "also had a March 733 which he competed in 1600 F3 and didn't use the BT38" so the Brabham was sold to Proctor who rebuilt it for son Seb Proctor to race in the 1992, 1993 and 1994 seasons. In 1994, Seb finished second in the series to David who was driving BT38C/20. Both cars were sold in 1998 via Peter Denty, but Proctor does not know who actually purchased them. By August 2003, both cars were owned by David Wenman when Mark Barton (Haslemere, Surrey) was due to drive "chassis 38", the other car being referred to as "chassis 37". Barton raced a BT38C at Brands Hatch in June 2008.
