Another way to tell if the RP is native to the stock is to look at the etching in the wood under the plate. There will be matching marks in the wood for every machine mark on the plate. If it is original to the stock it will be VERY hard to remove as well.
Thanks. In looking at the interior of the stock, it looks pristine around the area of the recoil plate. No scuffs or deformation around the recoil plate, just indentations where the plate resides. I am pretty confident this piece is original from the factory as the S/N is consistent when Underwood was delivering parts to NPM.
