For sale is this original .70" Marbles Peep sight post stem elevator. Years ago I acquired a large inventory of gun parts from an old gun smith that had worked at Marble Arms in Gladstone. He acquired a large cache of original Marble parts when he worked there, that is where this part came from. It's hard to find these original Marble parts anymore. Guaranteed to be an original Marble's part. Shipping in the US for $3.50.
