I have no idea if this a butt plate or not. It's iron and about 5 inches long. It has a slight curve to it and has two screw holes. I see no design or markings on it. Any input as to what this relic is and how old it is would be appreciated.
Thanks guys, I'll mark this one as solved. Good guess on the nameplate. That's probably what it is. I'll toss it in the scrap pile and move on to my next find...
