Claim: Cars pre chassis number 120 (approx), about April 1958, had similar bodies to the early Berkeley “Sports” cars,  among which could be the "Sports" type SA322,  on the other hand, cars manufactured from about April 1958 to the end of production had vertical front door edges and internal door hinges.
Evidence: It is probable that cars pre chassis number 120 (approx), about April 1958, had similar bodies to the early Berkeley "Sports" cars. Berkeley's first production car was the 'Sports' (type SA322), announced in September 1956 and produced from October 1956 to January 1957. Cars from about April 1958 to the end of production had vertical front door edges and internal door hinges, as well as body moulding and a few mechanical changes.
