Hey!
I'm glad to find such a resource as this site for BSAs. I don't own one as yet, but this one caught my eye the other day:
It was gone before I could act on it, but I was very inspired. I liked the combination of bits with the full width hubs, 2LS front brake, and chrome fenders. The ad didn't identify it well, indicating it might be a 1966 model (clearly wrong), but what is it exactly? I'd like to chase down something similar, as I'm about to finish a BMW Airhead project and I'm looking at a long rainy winter without a shop project.
