Judging from the amount of old photos I come across of BSA C10s, 11s and 12s there must once have been a lot of them around. Survival rate is not however very large: commuter bikes were generally run to the ground and then scrapped - there're probably more Vincent twins around these days than BSA C10s.

  1. You might be surprised just how many C10s are out there, as well as the C11/C12 lot,there is even a dedicated C series forum

  2. Thanks for the link Ken. I took a look and yep, I didn't imagine a forum for C10/ 11/ 12s could be so active. I guess like so many smaller old bikes you don't see them out on the streets so much.
