Crosslé 15F

The 15F is listed as a 1968 design but first appeared at the end of that year. The first two cars to leave the factory went to the US in October 1968, one for US Crosslé dealer Roger Barr and one for Ralph Loesser. A third car was being built in October 1968 and was due to go to the US but stayed in the UK and eventually appeared in 1970 UK series for Fred Saunders who used a Rover V8 engine.

Tim Osborne, owner of the Barr car and now also the Stanton car, is painstakingly constructing the history of all three cars and OldRacingCars.com is delighted to be able to publish the results of his work. All and any help would be gratefully received. Please e-mail Allen at allen@oldracingcars.com or Tim at tim@zentekno.com if you can add anything.

A note on chassis number identification

Paul Sheldon's Formula 1 Register Fact Book: Formula 5000 1968-1971 identifies the chassis number of the Fred Saunders car as 15F-70-04. Tim Osbourne's first car carries Serial Number C15F6839 and his second, acquired in 2004, carries C15F6840. According to the race-cars.com web site, the ex-Saunders car carries Serial Number C15F6942. The chassis numbers quoted above have had dashes added purely for the purpose of improving legibility.
