Here's the second new thread for Chevrons. Both a publication of where
I've got to and a plea for information.
The B20 was built as the 1972 combination F2/F3/FB car by Chevron.
However, the first car was built in 1971 as a development model and at least one was delivered new for the 1973 season.
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.
Help on what the plates actually said, on what car, would be greatly valued!!
Some chassis numbers are known, but they sometimes vary on what seems to be the same car and may not be altogether helpful. So I have labelled the cars by other distinctive characteristics and then included known chassis numbers including variants.
Of the BDA engined cars we know that Leppís British Atlantic chassis was initially fitted with a Richardson, that Gethinís works F2 car ran a Smith, and that Greenís car used in SE Asia had a Hart.
1: The 1971 development car [20.71.01]-Lotus t/c
According to an advert on race-cars.com this went to Fred Opert and was used by Bobby Brown in the 1971 Bogota GP, and subsequently by Brown and Jim Grob. Grob carried on using a Chevron B20 in SCCA [as both an FB and FC] for a number of years. Given the known histories of other Opert B20s it seems likely that this was 20.71.01.
Still extant in USA
2: The Skeaping car. [20.F3.1?/20.72.1?] [Lotus t/c]
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. Probably the B20 F3 for sale by Chevron A/S 2.8.73. Sold to Alex Lowe and used in British Monoposto and F4 series for a number of years. To Nick Crossley 1994. Currently for sale as having had only three owners [Skeaping/Lowe/Crossley].
3: The Lepp car [20.72.2/20.F2.1?]-BDA Richardson
MN report of the Mallory Park European F2 race says that Gethin appears in Leppís car for this race. This suggests that the Lepp car was earlier in the build sequence and the F2 cars were not ready in time. Subsequently used by Lepp in the British Atlantic series in 1972. Not known after this date, but by process of elimination [assuming nine built] the car used by Eris Tondelli in the European Hill-Climb Championship in March 1973.
4: The first 1972 works F2 car [20.72.2/20.F2.2]-BDA Smith
The regular works car for Peter Gethin in the European F2 Championship, sometimes taken over by Vic Elford. Both 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 his car has to be a distinct entity from this one. Won 1972 Pau GP. 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.
5: The first 1972 Opert car [Lotus t/c]
Delivered to Opert in April or May 1972. Used by Bobby Brown in 1972 SCCA pro championship. Given the known history of the other 1972 Opert car in 1973 this more or less has to be the car run by Joe Shepherd [Indianapolis] in SCCA and pro FB races in 1973 and 1974. Perhaps the car run by Peter Symond in SCCA in 1976.
6: The second 1972 Opert car [Lotus t/c]
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 had to have two new cars in 1972 plus the 1971 development model sold off to Grob. Canadian Motorsports Bulletin reports that the Robertson car goes to Peter Fergusonís Samsonite team for his girl-friend/team mate Linda Wilson in 1973. Sold back to Opert at some point, as f/s Opert, Formula June 75, p. 13, ex Robertson, Canadian Championship car. Could well be the mystery Price Cobb B20 in 1974, which appears at the same races as Shepherd and Ferguson [A B20 was recently for sale with 20.FB.14 stamped in the roll hoop, and described as ex Price Cobb, having subsequently raced in SCCA SW and SE regions to 1978.] Could be the Peter Symond car in 1976.
7: The second 1972 works F2 car [20.72.3/20.F2.3]-BDA
Appears at Oulton Park n/c F2 race for John Watson. In 1973 most likely the car of Nelson Todd in Irish libre races, 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 24.2.77 P. 15 says Parsonsís car is 'ex Kinnane'; and again MN 17.3.77 p. 8; then described as 'ex John Watson MN 9.6.77 p. 13.
8: The Ferguson car [Lotus t/c]
Appears at first round of the Canadian championship in 1973 for Peter Fergusonís Samsonite team; described as ďbrand newĒ in Canadian Motorsport Bulletin. Retained 1974.
9: The Green car [20.72.09?] [Hart BDA]
Appears at the Singapore GP [22.4.73] driven by John Green. Retained 1974 and subsequently to Steve Millen for 1975. A car with this chassis number is now in Australia and is thought to be Millenís car.

'Some days you eat the bear, some days the bear eats you.'
Car 9 , A 1996 letter from Dave Schollum to current owner details in many pages this car , brand new it appears to John Green [ John Green and Dave Schollum both worked for an offshore oil drilling co. in Japan] the car did the 1973 Singapore G.P. and probably ''The Gap '' hillclimb .
John Green died in 1974 and Greens wife contacted Dave Schollum regarding purchasing the car which they did , Steve Millen was contacted and flew up for the Malaysian G.P. in April, the car was shipped to Macau for the 1975 race and housed in the same garage as David Purley/Team Harper Modus. Either before or after Macau the car was shipped to NZ and fitted with a Cosworth FVC 1800cc.
In 1976 the car was sold to Ian Grey who had Caterpillar sponsorship and was painted yellow/black , he had car in S.E.Asia for about 3 years untill sold to Dick Ward in Perth Western Australia who was building a batch of sports sedans for export to the Phillipines and they used uprights / wheels etc as patterns .
Most of the components were rescued by the current owner with the assistance of Dick Ward and the car is now back to period spec owned by Harry Hickling of Canberra at the moment fitted with a Cosworth BDM [ injected BDD 1600CC. ].
FYI - I have listed that B20-72-6 was sold to M.Maublanc (France). This would have come from the Chevron Files that Roger Andreason has. I then have it listed in 1990 as Du Toya (France). Possibly something I stumbled across. Hope that helps.
Re Chassis No's. When I spoke to Paul Owens in 1995. He was very clear:
B20 - Model Type.
71 / 72 - Year.
# - being the Chassis No (I believe for the year, but back then I didn't know anything anyway, and not enough sense to properly clarify).
So you have a range of Chassis No's.
I believe that B20-71-1 and B20-72-1 are different cars. Making 10 definite cars raced / sold by the factory. B20-71-1 was the prototype car and you may have seen the photo's of it in the bare orange fibreglass body. No Splitters as per the Factory Cars and B20-72-9.
But to mix it up a bit the Race Records for many of the F2 events clearly have recorded Chassis No's B20-F2-2 and B20-F2-3. I don't know, but I assume if you have on the official race records that the Chassis No is B20-F2-2 then that is what would be on the car. I have all the race records and there is a definite sequence of events for each of the chassis No's.
B20-72-2 and B20-F2-2 is the same lineage of the Factory Gethin Car. Although possibly a couple of actual chassis's in this. Certainly photo's of the cars show some changes and the car was in a bad wall of death crash at Rouen. But just to confuse you all Ian Phillips writes back in March 1972 re the Watson drive at Oulton Park of B20-72-2 "being the hired works car and the fourth F2 chassis of the year". Which suggests that quite possibly some extra cars where developed. The car certainly had new body work by the end, wings and changed suspension from the original car.
B20-F2-3 was the Watson car. Probably renumbered and sold at the end. When I spoke to Paul he was quite adament that the Watson car was destroyed.
B20-72-2 has been owned by Roger Andreason for a long time and is in beautiful fully restored condition.
One last bit of trivia about B20-72-9 before I go. A couple of years back I purchased the remaining Factory FVC engine for the car. With the intention that eventually I will have it running as per Steve Millen Tasman Series Spec. As noted in the thread the Factory confirms that the car was sold new with the 1600cc BDA and after Steve Millen (Schollum Brother owned the car) it was sold to Ian Grey in 1976 who ran a Fuel Inject BDM in the car (As per current setup). From here the car went to Australia - never raced. Owned by Dick Ward in Perth, then in bits sold to myself. Now fully restored and on the race track again! At long last.
May I join in your discussions & ask for pictures & info about B20s. I have recently purchased B20 71 01 for restoration, this car was owned by Nelson Todd in Belfast from 2000 until Feb2006. I work at Crossle and am familiar with it, as I repaired the main steel spaceframe within the monocoque, the RH front corner having suffered accident damage. The project ground to a halt for various reasons and was sold to our agent in France, he also had to lay it to the side until he sold it to me in June.
This does contradict a comment that it is restored and looking great, I've no idea how that came about, I intend to call Nelson to let him know his car's back in NI.
I have the FIA papers & SCCA log books, the only named keepers are James Grob , Peter L Symonds until 3/8/75, Jack Van Dell - 3/8/85, and in Belgium, Pierre Haverland - 19/11/88. I intend to keep it as original as possible so any help would be much appreciated.
Firstly, I have attached a photo of Steve Millen in B20-72-9 during the NZ Tasman Series. And a good detailed photo of Peter Gethin's car - Front Suspension and Rear Suspension, to help show how the cars should be set up. B20-72-9 matches theses photos and I think all B20's will except for changes to the wing mounts and some early cars had armstrong shocks, but most with Pre-Set non-adjustable Bilsteins.
Secondly, for those interested in the Engine Listing in David Gordon's book: "Chevron - The Derek Bennett Story." It lists three 2 litre cars.
I just stumbled over an interesting detail: The John Green car, B20-72-9 is listed at the 1973 Singapore GP as Chevron B20 Hart. I had understood from Chevron Cars in 1997 that is was the 1600cc BDA-Richardson. So perhaps it is actually the 2000cc BDA-Hart detailed in David's book?
Also for B20-F2-3 / B20-72-8, Chevron Cars advised that B20-72-8 had a 1900cc BDG injected motor. This is the ex John Watson car.
