Tim,
You have the right maker, Eddie Meyers, Madison County, Ohio. He no longer makes the lock you have, or many other things, but at one time he hand made a number of locks, knives, bag axes etc. Quality is top notch and around here his stuff is in demand. I have a full stock Hawken rifle that was built with all Deer Creek hardware and lock and a WM Large barrel. His mark is a line with a dot at each corner. You won't go wrong using his lock on your rifle.
