I have a schwinn 3 seater in very good condition. I think it was probably made in the 40's or 50's. It was made in chicago and sold by Vincent's cycle. Has all origional schwinn badging and even schwinn pedals with reflectors on the 3rd set of pedals. I was trying to get an idea of how much it was worth. Does anyone have any idea? I could get pictures.

New Info
I think this was made after 1946. Serial Number is VC1723. Serial number is stamped on all 3 crank hangers and on left rear fork. Rim hubs stamped 767423 with some letters above that I can't read. Gear adjuster/tensioner and shifter stamped Campangnolo Gran Sport. I cannot find this serial number anywhere on the web as a Schwinn bike. All other indications point to post WWII. I am not sure if serial number stands for Vincents Cyclery. I took some pictures of it that I cannot add because they are larger than 100 kb. If this is not a real Schwinn it is a very good copy because everything on it says Schwinn except the seats.
Schwinn all over frame
Schwinn on all pedals
Schwinn on handles and tires
Schwinn on pedal hangers
AS on all seat tube clamps

If anyone has any idea what this is worth or anything else let me know. I can email pictures.
Thanks,
