Its a prewar hub, but the frame is post war, due to the rear drop-outs, all manufactures are guilty of using what ever parts they had laying aroung to build bikes. Schwinn for example would have never shut down a production line just cause they ran out of deluxe pedals, so they would just sub in anything they had, in fact there are stories of them running out of Black Phantom frames so they would take the painted Red or Green Phantom frames and just repaint them Black and Red. The bike is a lat 40's for sure. Hope this helps.
