I recently acquired whatI think is a 1944 Sporterized Remington O3A3. Whomever did the sporterization did a very nice job. The metal is all nicely polished and blued and it has a very nice monte carlo style walnut stock. The stock is stamped IMPERIAL inside the barrel channel and it has plastic buttplates and pistol grip caps marked BISHOP. I'm in the process of stripping the stock and applying an alkanet oil finish. The stock has a black plastic forearm end cap and the white line spacer has either shrunk or the end cap has shrunk. My question is how does the end cap attach to the forearm? I didn't really want to just cut it off without knowing something about it. I would like to put something a little nicer on the forearm maybe a horn end cap. Also I would like to get rid of the plastic butt plate and pistol grip cap and install steel ones. I was thinking of something like a Winchester Model 70 checkered steel butt plate. The butt of the rifle is completely flat, did Winchester ever make a flat butt plate for their rifles? Or maybe a horn butt plate. I'm just kind of looking to spruce up a very nicely done sporterization. Just running ideas through my mind right now.Any help would be appreciated
