1951 Cooper Mk V

This was one of the competitors in the Scratch Race for 500cc Racing Cars at the Vintage Sports Car Club's Richard Seaman Memorial Trophies meeting at Oulton Park in June 1981.

It's the 1951 Cooper Mk V of R.F.H.Wright with a 4998cc engine. After the Second World War motor racing in the UK was slow to re-start, partly because of petrol rationing and the cost of running a suitable car. Home-built ‘specials’ powered by 500cc motorcycle were created to provide a reasonably cheap way means of getting involved in the sport. John Cooper and Eric Brandon, with the assistance of John’s father Charles, decided in 1946 to build two cars, and in 1947 in the second post-war race meeting to be held Eric Brandon won the first race to feature 500cc cars. In 1950 this 500cc class of racing was adopted by the FIA as a new Formula 3, and John and Charles Cooper went on to build a series of these 500cc cars, eventually graduating to Formula 2, then Formula 1 culminating in Jack Brabham winning the World Drivers’ Championship in 1959 and 1960 in the 2½ litre Cooper Climax. There's a 500 Owners Association for all 500cc Formula Three enthusiasts, with lots of information about the different marques that took part.
