The rights to the Seven were sold in 1973 to Caterham Cars. Updated versions of this 1957 design are also produced by other speciality firms, including Westfield Sportscars and Donkervoort. Originally the number seven was applied to a Riley-powered Formula 2 car, but the vehicle was never completed in its original form, finally emerging instead as the Clairmonte Special, a two-seat sports car powered by a Lea-Francis engine.
