1957 Connaught B-Type single-seater
Connaught B10 is a continuation example of the rare B-Type Grand Prix car, constructed over a fifteen-year span by marque specialist Roger Hart and his team — engineers with direct experience restoring and preparing original B-Types. Built around a replica chassis originally made for Stephen Langton in the 1970s, the car incorporates a period Alta engine, ex-works dashboard and instruments from B3, and bodywork components sourced from B4. Its distinctive Monaco-specification nose cone sets it apart visually from standard B-Types. Supplied with an RAC MSA Historic Technical Passport dated December 2009, it is offered as a project requiring completion.
