1957 BRM P25

I took this photograph in the paddock at Aintree during practice for the British Grand Prix in July 1957.

It's the 1957 BRM P25 that was driven in the race by Les Leston who qualified in twelfth place on the grid, but retired with an engine failure after 44 laps of the 90 laps race. The BRM P25 was said to be the fastest of the 1954-1960 Formula 1 era, partly due to the oversquare (102.87 mm bore x 74.93 mm stroke) 2,491cc engine allowing for larger valves to be fitted. The car was plagued with reliability problems, however, and the only Grand Prix win was Jo Bonnier's victory in the 1959 Dutch Grand Prix.
