The first Crossley Mancunian was really the Alpha single-deck chassis which had been introduced originally at the end of 1929. From that date until 1937 it had a wheelbase of 16ft 7 1/2in, but in 1937 this was altered to 17ft 7in.
By the time it appeared under the 'Mancunian' name, the standard power unit had become a Crossley 8.367 litre 6-cylinder indirect injection oil engine. Transmission was via a dry plate clutch and 4-speed sliding mesh gearbox to an underslung worm driven rear axle, whilst the brakes were of the triple vacuum servo type.
This model remained in production until the end of 1939.
The Picture shows a 1934 Alpha of the Manchester Corporation, with a gas bag on its roof during World war 11. In many ways, the Alpha was very similar to the later Mancunian.
