Vintage Ten Speed All-Steel Bicycle Frame

Vintage Ten Speed All-Steel Bicycle Frame Good condition with the exception of one little notch where the pedal crank hit the frame. Includes the shaft for the crank and the bearings. I don't remember what brand of bicycle this came off of, but it was a bike of mine from 50 years ago. There are numbers which may help identify it. It is an all-steel frame, but is lighter than some of the steel frames I've seen.
