Derrick Colvin was born in Scotland but came south to Yeovil in Somerset in about 1952 to work as a test pilot with Westland Helicopters. He became interested in racing and started with his Invicta, then an Allard and an MG. In 1956 he bought his first real racing car, a Cooper JAP. Very definitely a club racer, Derrick raced for fun, the JAP engine in his Cooper would have thoroughly outclassed in '56.
