BSA's 'C' range of lightweight machines was introduced in
1938. Similar in many ways to those of the larger 'B' range, whose wheels and
brakes were employed, the cycle parts consisted of a simple diamond frame and
girder front fork. First model was the C10 sidevalve single with coil ignition
and three-speed hand-change gearbox. A de luxe C10 with foot-change gearbox
joined the range in 1939, as did the overhead-valve C11, and when war broke out
in September of that year BSA's entire stock of 1940 models was requisitioned by
the War Office for military use.
