Hello All..Im new to the forums, and have a question. I just picked up a 1966 Victor441 Enduro..Matching numbers on frame and motor. Mine has B44E1037 I have been told that my # could possibly be the 37th Victor441 built? Im asking on here as i do not know how the # system for this model BSA are listed in the order of production? Is there a website or book that someone can tell me of to research more info on my bike? Appreciate any help. Cheers Keith
