Alvis 12/50

The Alvis 12/50 was a four-cylinder car introduced by the Alvis Car and Engineering Company in 1923 and built through a series of versions until 1932. The first cars, coded SA and SB, carried an overhead-valve engine of 1,496 cc and later 1,598 cc in a subframe bolted to a ladder chassis, with brakes on the rear wheels only. The SC of 1924 made the larger engine standard and offered front brakes, and a stronger redesigned chassis followed from 1925 with the TE and TF. Carbodies and Cross and Ellis built factory bodies in two- or four-seat form, open or closed, and the most famous was the Super Sports two- or three-seater nicknamed the duck back.
