Crossley badge The Crossley "Arrow", "Six" and "Alpha" single deck buses

 

The "Arrow" range of single deck buses was introduced in September 1929. The name was changed to the "Six" in April 1930 and then to the "Alpha" in September 1931. The "Arrow" name was dropped because it was owned by Dennis.

135 petrol engined chassis were produced with numbers 90201 to 90300 between 1929 and 1931 and 90601 to 90635 between 1930 and 1931. Two Diesel versions with VR4 engines intended for export were also made in 1933 numbered 91101 intended for New Zealand, but never shipped, and 91102 which went to Perth, Australia. 

Twenty Five further chassis numbered 91901 to 91947 made in 1934 and also called "Alphas" in publicity material were in fact Mancunians.
