I got my "found" bike home from the shop today. When I first brought it in there I told the mechanic about the chain-of-events and history of the bike and how I'd been the original owner and had just found it sitting alongside the road in a nearby neighborhood with a "FREE" sign on it. He took extra care in the re-build and it turned out beautifully. It looks pretty good for a bike that I'd originally bought back in the 1970's. The serial # of it is: Y1N1659. I'm gonna see if I can learn when it was built.
