Clothed in stylish bodywork by Stanley Riley, the Coventry marque's pre-war offerings were among the world's finest small-capacity sporting cars.

Percy Riley's 9hp, 1,087cc, twin-camshaft four was an outstanding engine design by any standards, various versions powering Rileys from 1926 to 1957.

The twin-cam Riley engine was one of the most advanced of its day, so it can have caused little surprise when the Coventry manufacturer created its first six by, in effect, adding a pair of cylinders to the existing design.

Hailed as 'The Wonder Car Plus Two', the first 14hp, 1.6-litre six-cylinder models duly appeared in 1929 followed by 12hp, 1.5-litre versions in 1933.

Riley's 1,633cc, 13.5hp engine was also offered in this chassis, which was built in two different wheelbase lengths (110.3" and 113.5") and was available with a wide variety of bodies in different styles including the Alpine, Kestrel and Mentone saloons, Lincock coupé, Ascot drophead coupé, Lynx tourer and March Special.
