I found a bottom end for a WC-11 BSA stamped WC11-588. Gearbox plates are attached and has green paint so presumably War Department?. Does anybody out there have some details as to date of manufacture, numbers made, production span etc.?
I think it is common knowledge that only 530 C11's were issued as WD bikes and supplied to the India Office in 1940. As far as I know, none have survived? The Engine numbers are WC11 4001- WC11 4531. Ron
