The ebay stock is not for an "old" super, and the serial number is hard to read but it may be from the peak of the salt wood era. Also it may well be from a trap model gun with not much drop. I am pretty certain the Art does not do stocks and sends them out. At one time I read he sends them to Show-Me stocks, but not certain about this. If you want to duplicate the existing stock, the better pantographs will come very close, leaving only minor fitting, finishing and checkering. Still probably in the $2000 range.
