I just traded for this 26" Schwinn Skipper earlier this Sunday, but I'm thinking of either selling it or trading it for something else. I know it was built on April 4th, 1961 according to the serial number, but I don't know how much of the bike is original, outside of the paint. If anyone can give me an idea of how much it's worth/what I could sell/trade it for, please let me know.
