Hello everyone! I come from Poland and I have been following your forum for a long time. I have a few questions about the BSA model WM-20. I have this model probably from 1940. Frame number is: WM20 10709 and engine number is SA 970.
My question is the contract (C) number on the tank. If you manage to find some informations about the history and C number of this motorbike that will be awesome.
I look forward to hearing from you. Greetings from Poland-Szymon.
