This is the record for B20s that is waiting to go onto oldracingcars.com
All sources suggest that nine were built, and the following engine configurations are given for these cars:
1 BDA Smith; 1 BDA Richardson; 1 BDA Race Engine Services; 1 BDA Hart; 5 Lotus t/c.
The t/c engines would have been fitted to the FB cars in 1972/3 and to the solitary F3 car.
Of the BDA engined cars we know that Lepp’s British Atlantic chassis was initially fitted with a Richardson, that Gethin’s works F2 car ran a Smith, Watson’s F2 car the RES, but Green’s car used in SE Asia was fitted with a 1600cc Richardson BDA when delivered. The figure of nine seems, however, to discount the 1971 development model, so the total production appears to be ten. All but one of the cars are known to survive (and the South African car may well be out there), but complicating the situation is that there are thirteen chassis numbers for the ten cars built. This is because Chevron seem to have allocated duplicate plates for the three cars built to F2 spec. These numbers seem to correspond as follows, 20-72-02 to 20-F2-2; 20-72-08 to 20-F2-3 and speculatively 20-72-09 to 20-F2-1. These F2 plates are observed at times on cars that seem, on the basis of their other appearances, to carry the other plate. 20.F2.1 is more problematic, but it seems possible that the 20.72.1 given for Gethin’s car at the BARC 200 at Thruxton was in fact F2.1, since 20.72.1 is clearly assigned to Skeaping’s F3 car which was in another race that day. We suspect that this was the works test chassis for much of the season, and rebuilt into a late season production model for export to the far east.
20.71.01 According to an advert on race-cars.com this went to Fred Opert and was used by Bobby Brown in the first 1971 Bogota GP, and subsequently by Brown and Jim Grob. Although a number of B20s were on the entry list for Bogota this seems to have been the only one to appear. Grob took over the car at the Road Atlanta race of the SCCA FB series in early July 1971. Grob carried on using a Chevron B20 in SCCA [as both an FB and FC] until 1974. Given the known histories of other Opert B20s it seems certain that this was 20.71.01. According to log book then to Peter Symonds who kept it until mid 1977, when offered for sale, Formula May 77, p. 60 Pete Symonds, 246 Wethersfield St, Rowley MA 01969, ‘Chevron B20, white’. Then to Jack van Dell, according to log book. To Pierre Haverland (Belgium) in 1988 and advertised on race-cars.com in 1999. Sold to Nelson Todd in Ireland. Mick Henderson 2007
20.72.01 A semi-works car run by Chris Skeaping in the British F3 series. Finished in February 1972 so assigned the first number in the 1972 series.
Used by Skeaping for most of the season. Chassis number given by F1R for Gethin’s F2 car at Thruxton BARC 200 at Easter 1972, but MN reports later in the season speak of Elford and Gethin’s car at European races as having been this car, whilst giving the 20.F2.2 and 20.72.02 plate numbers, so this is probably an F1R typo.
Probably the “B20 F3” for sale by Chevron, A/S 2 Aug 73 since this was the only F3 car in the B20 series. Sold to Alex Lowe and used in British Monoposto and F4 series for a number of years. To Nick Crossley 1994. For sale 2007 as having had only three owners [Skeaping/Lowe/Crossley].
20.72.02/20.F2.2 The regular works car for Peter Gethin in the European F2 Championship, sometimes taken over by Vic Elford when Gethin drove in the BRM F1 team. All sorts of chassis numbers are given in race reports suggesting that a certain amount of plate or chassis switching took place, but since Lepp is racing regularly in Atlantic with the only other early season BDA engined car (04), his car has to be a distinct entity from this one.
MN 24 Feb 72 p.18 publishes photo alongside: 'Another new single seater to be tested at Silverstone last week was the Chevron B20 which Peter Gethin is to drive in the Euro F2 championship. Fitted with an 1800cc Alan Smith BDA Bennett did a dozen or so laps in the damp as Gethin was still suffering from the after effects of flu.'
MN 16 Mar 72 p.9: chassis number given for Gethin’s car at Mallory Park. A/S remarks Alan Smith BDA and no time to sort car 16 Mar 72 p.34. Chassis number 20.72.1 given MN 6 Apr 72 pp. 10-11 for Gethin’s car at Thruxton. A/S chassis number not given; but ‘virtually untouched since Mallory’. At Nurburgring Elford drives [MN gives chassis B20-1; A/S 4 May 72 p. 28 says Elford entered in 20.72.2 which Gethin normally drives].
At Pau Gethin drives [A/S 11 May 72 p.13 says the Alan Smith powered car used by Elford at the Nurburgring; MN 11 May 72 p. 5 says 20-F2-2 [number given] ‘used the previous weekend by Elford’.] At Crystal Palace, Elford again drives,
A/S 1 June 72 p. 14 says 'in the works Chevron which he used at the ‘ring and which won at Pau with Gethin'. MN 1 June 72 p.14 says ‘Elford back at the wheel of Gethin's Pau winning B20, the car absolutely unaltered'. At Rouen Gethin is back and has a bad accident [‘write off’ A/S; ‘badly damaged’ MN].
Gethin then appears in a car of unknown plate at Hockenheim, 9 July, Imola, 23 July, Mantorp 6 August. Watson takes over at Brands Hatch ‘Rothmans 50,000’ 26 August, Gethin again at Salzburgring 3 Sept, and alongside Watson in the new 72-F2-3 at Oulton Park 16 Sept, Gethin at Hockenheim 1 Oct 72 has a chassis number given as F2-2 by F1R.
Taken to the South American series for Dave Morgan. Sold to Tony Martin in South Africa in 1973 from there in a deal that also involved a March 722 and Brabham BT38. Run for Glenn Martin in South Africa in 1973. Subsequently unknown.
20.72.03 Perhaps delivered to Opert in early 1972. Used by Bobby Brown in 1972 SCCA pro championship after the 1971 car is sold to Grob, and perhaps before this, including the Japanese GP at Fuji, and perhaps the second race at Bogota. (Brown's car in the first race has orange bodywork and in the second, blue) All Opert B20s seem to have been sold at the end of the season. At Caracas in early 1973, when virtually every car in Opert’s shop seems to be entered, there are no B20s in the list.

Roll bar stamped 72 FB 14 [this is an SCCA region stamp for Las Vegas region in SoPac division, not the chassis number]. Ad said ‘Raced in SE & SW SCCA to 1978’ with driver Paul Lindell (which would accord with the roll bar stamp).

Richard Jackson for sale Autoweek 28.2.76 p. 22 by Jackson 12888 Noel Road, #2085 Dallas 75320 is a B20 with t/c and BDA photo shows, car has race no 2 on it, red or blue, and the modified nose that's conspicuous on the car in the race-cars.com advert.
Autoweek 30.8.75 for sale by Richard Jackson of same address seliing a B20 only here it is described as 'ex Brown' . This cannot be the first Brown car 20.71.01 as that's known to be with Symonds at this time.
early 75 Autoweek we have for sale by "Price" 20305 Mosscrest Dallas TX Immaculate Chevron B20. This seems to have been Price Cobb and would be the car he ran in 1974 with Freeman Racing.
Before that probably the B20 of Chip Mead in 1973. There are only two B20s unidentified in 1973, those of Mead and Joe Shepherd. Shepherd doesn't sell his until 1976, indeed it's for sale Autoweek 17.1.76 p. 29 3901 College Ave Indianapolis 46205, so 03 must be Mead's car. And since this car was originally Brown's it suggests that Shepherd's was the ex Lepp 20-72-04.
Now with Steve Marschman (USA)
20.72.04 Used by John Lepp in the British Atlantic series in 1972 with a Richardson BDA. Exported to the US at the end of the season fitted with a Holbay t/c. [Thus providing the Richardson tuned BDA that is fitted to Green’s 20.72.09!]
This more or less has to be the car run by Joe Shepherd [Indianapolis] in SCCA and pro FB races in 1973 and 1974, since his history with a B20 runs parallel to the Cobb/Mead car but would have a Cen Div stamp. With Roger Andreasson (UK) 2003
20.72.05 Delivered to Opert in May 1972. Used by Brian Robertson to win the 1972 Canadian championship. (Since they never appear together, Robertson and Brown could have been using the same car. However, in 1973 the number of B20s appearing together suggests that Opert must have had two new cars in 1972, both of which were then sold on, plus the 1971 development model sold off to Grob. CMB reports that the Robertson car from 1972 goes to Peter Ferguson’s Samsonite team for his girl-friend/team mate Linda Wilson in 1973. Sold back to Opert at some point, as for sale by Opert, Formula June 75, p. 13, ‘Chevron B20 ex Robertson, Canadian Championship car’. (Probably in part exchange for his new Chevron B29.)
Owned by Ed Swart 1989, so cannot be the Cobb-McKay car.
20.72.06 Sold to Pierre Maublanc for the 1972 European hill-climb championship. Used by Roger Damaisan the following year, and then sold to Guy Baria. [Echappement report of Sisteron Saint Geniez hillclimb 21 July 74 says Baria’s car is ex Damaisan.] Possibly via other owners to Patrick Caisson, 1982 he used it as the basis of a Renault engined special saloon. Sold by Caisson in 1989 to Dutoya (France). Sold to Rupert Marks (UK) in 2001.
20.72.07 Said to be a late season car for Brian Robertson, replacing 05. However, perhaps used only once and then to Peter Ferguson, used at 1972 ARRC and throughout the 1973 Canadian season. If so, retained 1974, running both seasons with Samsonite sponsorship. Known to have been owned by Alex Polsinello (Canada) in 1991, so again cannot be the problematic Cobb-McKay car.
20.72.08/20.F2.3 Appears at Oulton Park 16 Sept 1972 for John Watson fitted with 1980cc RES BDA. Carried the F2-3 plate. In 1973 most likely the car of Nelson Todd in Irish libre races, fitted with a BDG engine, and then used by Jim Sherry, Mike Nugent and Richard Parsons in successive years of the Irish Atlantic Championship. There is an established provenance from Todd to Parsons. MN 24 Feb 77 p.15 says Parsons’s car is 'ex Kinnane'; and again MN 17 Mar 77 p. 8; then described as 'ex John Watson MN 9 June 77 p. 13. Sold to Tom MacMillan to Bill Lord (Scotland) 1978 for Scottish Hillclimb Championship, and retained 1979. Lord advised in conversation with Steve Wilkinson that the car was subsequently sold to a business man who was buying up Atlantic spec cars to export to India.
20.72.09 Bought new from Chevron by John Green (Singapore) in early 1973, fitted with 1600cc BDA. Only raced in 1973 Singapore GP. Green died in 1974 and his widow sold the car to Schollum brothers for Steve Millen to use in S.E. Asian races and the 1974/5 Tasman series with a 1940cc FVC engine. Sold 1976 to Ian Grey (or Gray) and fitted with fuel injected BDM engine. Used by Grey for some years in S.E. Asia then to Dick Ward (Australia) and current owner Harry Hickling.
