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.

[1] In slightly modified form, it went on to be manufactured between 1932 and 1936,[2][3] during which time 148 cars were built.

Walmsley Lyons and Co, as SS Cars Limited, purchased Swallow at the end of July 1934.

The SS 1 was noted for its apparent value for money and its attractive appearance, rather than its performance.

With a top speed of 75 mph (121 km/h), the cars were remarkable for their styling and low cost rather than their performance.
