Grand Prix of Oklahoma

War Bonnet, 16 Jun 1968

All cars are 5-litre F5000 unless noted.

Notes on the cars:

1. Brabham BT6 (Charlie Adams): Charlie Adams (Manhattan Beach, CA) campaigned a Brabham Formula B car from late 1965 through to early 1968 when he replaced it with a new BT21C and it is assumed that he ran the same car throughout that period. A report on the May 1968 CDR Pro race in Finish Line identified it as a Brabham BT6 and Adams described it as a 1963 Brabham when he advertised it in CP&A in April 1968.
2. Brabham BT21A [4] (Dick Smothers): Sold new to Lou Sell (Fullerton, CA) for US Formula B in 1967 (three Pro races only), then to his backer Dick Smothers (Woodland Hills, CA) for 1968, although Sell also raced it in one SoPac National early that year. To Fred Opert late 1968 in part-exchange for a new Chevron and from him on to Ken Duclos (Boxboro, MA) for 1969. Duclos believes he returned it to Opert at the end of 1969 when he acquired his new BT29 and it next turns up in 1971 with John Sorbello (Lafayette, MA) who widened the cockpit section into a two-seater and added a Chevron B16 body. Later to John Kauffman thought he had bought a Chevron and then to Joe Maria in the early 1990s. It was restored by David Irwin to BT21A spec and was still with Maria in 2007.
3. Brabham BT21A (Joe Alves): Joe Alves (Sherman Oaks, CA) raced a #66 Brabham from the start of 1968 to mid-1969, finishing fourth in SoPac FB in 1968 and fifth in 1969 and it is assumed that he had the same car throughout. It was identified as a BT21A by Bob Schilling in his report on the Riverside Regionals in early 1968 (Post Grid Vol 6 No 2). The car is likely to have been a new car delivered late in 1967 rather than second-hand.
4. Brabham BT21A (Bill Simpson): Bill Simpson (Los Angeles, CA) bought a new Brabham BT21A during a trip England over the 1967-68 close season to replace his FB-spec Lotus 51. He raced the car in west coast SCCA and FRA events during 1968, usually as #58.
5. Brabham BT21A (Ray France): Ray France (Inglewood, CA) raced a silver Brabham BT21 during 1968 and 1969, entered as #2 by Centaur Racing Associates. The car was later revealed by an advert in Oct 1969 to be a BT21A. This may have become the basis of the blue-and-gold #29 "Centaur Brabham" raced by France in 1970.

Sources

The identification of individual cars in these results is based on the material presented elsewhere in this site and may in some cases contradict the organisers' orginal results.

1968 US information has been taken from SCCA results sheets with additional information from Autoweek race reports and from some entry lists. Thanks to David McKinney and Wolfgang Klopfer for providing these. Identifying the classes and model of some entries has proved very difficult so all new information would be welcomed.

1969-1971 US information has been collated by Chris Townsend using Autoweek reports. All comments, clarifications, corrections and additions are most welcome.

1972-1976 US information was originally collated by Wolfgang Klopfer, converted to database format by Dawn Harrison and checked by Jim Thurman and Don Capps. Wolfgang's main sources are Autoweek and individual SCCA results bulletins but Autosport, Autocourse and Road Racing Annual have also been consulted.

US SCCA Run-Offs, Nationals and Regionals results were collated by Wolfgang Klopfer from Autoweek reports. These reports were usually very brief so the information on the majority of races is limited just to the identity of the FA class winner.

Some race programs have also been used for entry lists and other information. My thanks to Richard Coe for the generous contributions from his collection.
