1963 Lotus 23B

This car competed in the Historic Motor Racing News Gentlemen Drivers Sports Racing Challenge race at the Gold Cup meeting at Oulton Park in August 2005.

It's not listed in the programme of the event, but it's Marshall Bailey's 1963 Lotus 23B. The Lotus 23 was introduced in 1962 to compete in the smaller classes of sports car  racing and was used with engines with capacities ranging from from 750cc up to 1600cc. It proved to be an extremely successful car and about 130 examples of the Lotus 23, 23B and 23C were produced between 1962 and 1963.
