Its too bad that set was in such poor shape to begin with. Since the set was not refinished professionally to duplicate the original finish it would bring the value down abit and it would have been better if the caps were re-stuffed with the new ones. The set is very much worth the time to have had the refinish and the electronics done with more attention, if I were him I would just keep the set now, I dont think he will get the price he wants for it so might as well enjoy it.
