I would hope that you at least have some idea of what the values are. There have been a few B6s listed recently, a number of prewar Schwinns have sold in the past which establishes value, I recently sold an '07 Racycle here. I think it might be worth your time to invest a few hours searching the forums, Ebay sold items, and the Copake online auction catalog past results. I would also hope you have a decent working knowledge of what is, or isn't, correct on these bikes--especially the Racycle. I'm sure you've heard the old proverb "Give a man a fish and feed him for a day. Teach a man to fish and you feed him for a lifetime. Good luck in your pursuits. V/r Shawn
