Greg,
I am a Schwinn Factory Grad from 1969 and was fortunate to go with my grandfather. It was fun to look back on those days and now realize that I have been in bicycle business 40+ years of my 49 years. I have all of the factory manuals from that era and before. It's great when one of my employees can't figure out how to work on the vintage bicycles and I can give them everything they need to know to make it work.
