I was getting ready to start on another bike project and was moving this one when I noticed the serial number under the crank was rubbed clean. I decided to look up the number. The number is, "F57267". I'd never considered it might be an old Schwinn but I found similar numbers in the 1949 Schwinn numbers listing. When I started to give it a little closer inspection I found an 'AS' bolt on the seat post clamp. One thing that puzzles me is the strange sprocket. I suppose it could have been changed at some point over the years.
Any thoughts on this would be appreciated.
