J.B.S. stands for James Bottoms and Son. Developed by Alf Bottoms, a former speedway rider from London, the J.B.S. 500 was developed from the Cowlan Special of Coward and Lang. The first prototype was built in 1950 for Andre Loens, it features all round independent suspension using unequal length wishbones, a multi tubular chassis and mid mounted engine. Alf, himself became the lead driver and was joined in early '51 by Ron "Curly" Dryden. The pair achieved a one-two at at the Earl of March Trophy in March effectively giving notice of the car's potential.

About 20 cars were built and they became highly competitive and looked set to present a consistent challenge to the Coopers. Tragically, the project lost much of it's momentum when Alf was killed at the Luxembourg Grand Prix in 1951. This was followed by Dryden's death at Castle Combe in October.

The most notable drivers were Peter Collins and Don Parker and Frank Aikens also raced J.B.S. A modified J.B.S. with swing axle rear suspension by Ray Martin became the Leston Special.
