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 intended for export
were also made in 1933 numbered 91101 and 2.
Twenty Five further chassis numbered 91901 to 91947 made in 1934 and also called "Alphas"
in publicity material were in fact Mancunians.
