Saloon, 4-light special coupé.

The big guns in the Series range, both sharing identical body and chassis. Smaller bore version of the Twenty-Five's sidevalve unit used for the Twenty-one. All have three-speed 'boxes, and there were Easiclean wheels from end of '36. Only 829 Twenty-Ones made before the model discontinued at the end of 1936. Find one of the four-light special coupés and you've really got a rarity, as only thirty so were made.
