This is a '39 Model C Frame in the 16" size. Nice straight frame with no issues. I already have one like it, so I did not need a duplicate. This has the nice line of the top bar due to the shorter seatpost tube and makes a slick ride. Serial # is A80118 and is for the frame only. It could be yours now for $150 Shipped REC These do make a very nice riding bike, and IMHO are quite nice to look at as well. The photo below is the one I built from the other frame I already had and is NOT FOR SALE! It is merely an example of a not outrageously expensive finished piece.
