Acer, that's correct, it's definately not a Siler, or L7R, or Davis, and maybe restore isn't the correct word. It 's a match to some of the locks used on a number of the Susquehanna guns. It's all there, and I want to just make it useable, and it is in almost workable condition now. I think I'll start with a disassembly, and ultrasonic cleaning. None of the holes seem to be hogged out, and other than the deep notch at full cock it appears to be in good condition. Could the notch be filled, and recut, or would it be better to get a new tumbler, and sear.
