As of tonight I own this bike! I have actually been back and forth with the seller for a couple weeks, and we finally reached an agreement. I don't know a lot about it. He believes it is a Schwinn, unknown model. At a guess, I would say the handlebars, seat, pedals, and missing front fender are not original. The frame, fork, wheelset and cottered crank look like they probably are. Rear fender and chain guard have a strange texture, so if they are original they have been painted and not professionally.
