It could be a '37 from the looks of the chainguard. I don't think that seat came with that bike. Seat is from a '37 Schwinn SA 207 or a '38 Deluxe cantilever autocycle. High dollar seat!! I don't think the neck, fork, or truss rods are Schwinn. Schwinn had a similar neck but it was aluminum. So, a parts bike with some darn good parts. Gary
