1950Lou,

Jim Carter sells used wheels (look for "USED PARTS" in their catalog's index.

If you order from them, let them know the quality that you will accept. I have had 50/50 luck in getting junk vs useful used and remanufactured parts from them (they take back stuff you do not like but it is a waste of time and effort and shipping costs).

Good luck,
Tim
