I don't know enough about vintage bikes to comment, but I can say that when I lived in Paris as a young adolescent riding on my 125 CC Lambretta, I saw the only Norton I've ever seen on the street. I don't know which model it would have been — this was in 1958 — but as it and my uncle's 1948 Harley were my first introductions to MCs, it would have to be one or the other.

Thanks for the links in this thread. Seeing as it isn't that far to the Barber Museum, I'll see if I can get the boss to approve a weekend up that way this fall.
