Thank for all the great info so far. I measured the Seat Tube at 28.0 and the stem 22.0, so it`s French I would assume. The bike has 27 inch wheels. The front wheel is a newer alloy wheel that looks like it came off an 80's Schwinn or something. The rear wheel has a Rigida chrome rim with a Normandy hub. Would this bike have come with 27 inch wheels or 700 C wheels? I will want to replace them with a better set of wheels that would be more period correct.
