Seems every old harley was stolen in the states at one time!
Actually old dealers and owners were responsible for a lot of that screwy number stuff.
The one shown has matching '56 case numbers, and a '54 front fender emblem. A little schizophrenia going on there!
And it seems the Brits just changed numbers whenever they liked to match log books and V5s. Numbers are actually inspected here for originality, you guys don't seem to care!
