Thinking of taking a look at an 850 Commando with the frame/engine # 305548/308170. This suggests to me that the frame was manufactured in mid to late 1974 and the engine was made in early 1975. I understand that all of the Nortons match until around 1974 -- can anybody tell me whether this could be the original engine, or if not, what I should look for when I examine the bike? Thanks!
