I have an original Lorenz musket marked 861 or 2 on the lock plate that family legend has it was carried in the war by a family member and it came home after. It has had about 18in of forend removed, and is missing the front two barrel bands, ramrod and rear sight. Can anyone tell me what the dovetail sizes were for the fixed and folding rear sights on these? I am throwing around the idea of restoring it to as close to its original appearance was and bring it back to full function.
