I was recently given a family musket that has been in my family for years. I was told my great great grandfather modified it to percussion to put down hogs to butcher. Other than that I have little information. Can anyone help me find when and where this was made and by who? (Picture #8 has a name engraved). Also does anyone know where I can find replacement parts for it? It is missing small decorative pieces and the patch door. Any help is much appreciated!
