1975 Sauber C4

This car competed in the HSCC 2 litre Championship race at the Historic Sports Car Club's Summer Race Meeting at Oulton Park in July 1992.

It's the 1975 Sauber C4 of Ian Giles, and the only information about it in the programme of the event is that it had a 2,000cc engine. This is chassis 75-C04-001, the only C4 built, and it was raced in 1975 mainly by Harry Blumer, finishing in third position in the Swiss Sportscar Championship. The car has an aluminium monocoque chassis instead of the tubular frame of the earlier Sauber cars, and has a 1,795cc 4-cylinder inline Ford Cosworth BDG engine.

Gurney Eagle FA74

This is a photograph taken at the Gold Cup meeting at Oulton Park in August 2005. One of the races at this meeting was for the HSCC Derek Bell Trophy, and this is one of the Formula 5000 cars that took part in that race.

It's a 1974 Gurney Eagle FA74, and this is what the programme of the event said about the car:

'Californian Dan Gurney's legendary All-American Racers team was out of F1, concentrating on USAC champ cars and F5000 by the early 1970s. This striking Chevrolet-powered machine was raced by Elliott Forbes-Robinson, whose team mate was occasionally James Hunt. It is owned by former TGP race winner Ian Giles.'
