The bike that is closest to showroom condition that I know of, is the Bob Chantland Series C Shadow. That bike, and the Shadow my father bought new, were both built in late 1952, and both left the factory the same day, in the same delivery to Indian Sales San Francisco. Both bikes where originally sold from dealers in the Los Angeles area. My father rode his bike for only a few years, about 17K miles, then had an issue with the motor, took it apart, and it then sat in our garage until the early 1980s. The Chantland bike was purchased by someone that rode the bike for way less miles, less than 3K miles. I am not saying all bikes had crimped ferrules, but these two bikes have crimped ferrules, that I believe are factory. Pictures ferrules1 and 2 are of the Chantland bike, and A-D are my Shadow. Yes, even those few years my father rode his bike, he did change a few ferrules to thumbscrew clamps, but those 50's era clamps survived untouched, most or all of the other ferrules are untouched as well. Some of the herringbone on my Shadow is from 60 years ago.
