Here is a "restored" one I thought went for a reasonable amount of money recently. Given the ample wall thickness on the 2 Greener's I have, I wasn't too concerned about wall thickness on this one despite some refinishing over pitting in the barrels. Think this would have made a nice first shooter for someone. Looks decent and should perform well.
