I compared the 2 94"s side by side. The 32 S is about 1" longer than the 30-30 of the same design. Apparently some previous owner simply removed the original steel butt plate & glued a rubber pad on.
Might try & saw the rubber pad off. What would be the possibility of finding a correct butt plate? If I try & do a little refinishing of the stock I could remove the sling swivel & fill the hole. Or I could leave the rifle sling in place. Decisions decisions. Still doesn't explain the serial number vs caliber question..
