Beginning in 1954, company manager and racing driver Brian Lister brought out the first in a series of sports cars from a Cambridge iron works. Inspired by Cooper, he used a tubular ladder chassis, de Dion rear axle and inboard drum brakes. Like others, he used a tuned MG engine and stock gearbox. It made its debut at the British Empire Trophy at Oulton Park in 1954, with former MG driver Archie Scott Brown at the wheel. Later, Lister swapped in a Moore-tuned Bristol two-litre engine and knockoff wire wheels in place of the MG's discs to improve performance. For the sports car race supporting the 1954 British Grand Prix at Silverstone, Scott Brown won the two-litre class and placed fifth overall behind only works Aston Martins.
