The SS 1 (the top of its radiator says 'SS One') is a British two-door sports saloon and tourer built by Swallow Coachbuilding Company in Foleshill, Coventry, England. It was first presented to the public at the 1931 London Motor Show. In slightly modified form, it went on to be manufactured between 1932 and 1936, during which time 148 cars were built.
