context_page_description: The Alvis 12/50 is a car introduced by British business Alvis Car and Engineering Company Ltd in 1923. It went through a series of versions, with the last ones being made in 1932. A range of factory bodies could be specified in two- or four-seat form, with either open or closed bodies.
context_section_description: The 12/50 was redesigned for the 1926 model year. From Autumn 1925 a new stronger chassis was used for the TE, which had its engine (now built around a redesigned crankcase) enlarged again to 1645 cc, and the TF of the same year with a short stroke version of the same engine, displacing 1496 cc.  A single-plate clutch replaced the previous cone type, and for these and all subsequent 12/50s the engine was bolted directly to the flange-frame chassis, dispensing with the subframe of previous models. From the TE and TF models onwards four-wheel brakes were fitted as standard, single-shoe drums on the rear replacing the double-shoe drums of the previous model. The TE and was superseded for the 1927 model year by the TG. Confusingly, the short-stroke TF was replaced in the 1927 range by a car with an 'S' prefix: the SD.
