640B Original or a Rustoration?

 

Looks like a period photo doesn’t it well it is not, a lot of motorcycles are restored from photos that are supposed to be genuine of the era. There are a number of restored machines that are not as the maker intended, that is not to take credit from the owner that has lavished piles of money and time on their treasure but be careful if you are buying such a machine because it may not be as original as you think, the term “Rustoration” is when it is old and rusty but not as old or as rusty as you think as someone has gone to the trouble to make it that way. How many of things can you pick with 640B above that are not correct & I still would love to own it
