Hi all. First post.
This is a picture of my father in the early 60s.
I'm keen to properly identify the bike.
I think it's a c10 or c10L but I'm not totally sure. Hoping others with more knowledge would help identify.
Kind regards
Andrew
Looks like a C11G - you can see the rocker box, so overhead valve, and the primary chaincase bulge to take an alternator.
Thanks very much.
