Tom Clarke was born in Bristol in 1912 and was one of the first "impecunious enthusiasts" to acquire an Iota chassis to build his first special, CBP I. The Iota's were quickly outclassed by production cars from Cooper, JBS and Kieft so Tom had limited success. Tom was also responsible for new trend with his "Special Mobile Unit", in reality a converted caravan used for transporting his car and accommodation.
Some results for CBP I
Towards the end of 1951 he constructed a second car, CBP II, using swing axle and rubber band suspension at the rear and a forward driving position, in the style of Martin and Kieft, powered by a JAP engine. With this car, he achieved rather more success.
Tom Clarke seems to have quit racing at this point but thereafter led an active life, becoming Mayor of Bristol in 1979. He passed away in January 2015
