Hello - I am looking for an expolded parts diagram/schematic or other picture that shows the inside parts and how they fit together on an H&R arms co Hunter model double action revolver. It is a .22cal 7shot with a 10 inch barrel. My dad recently gave me one that is in need of repair. I am thinking that there are parts that are missing/broken. I know there is little $$ value to this gun - more personal value if I can get it fixed. I have worked on most of my own guns over the years and if I can get the diagram - I think I will have a good shot at fixing this one. Will be a great project for me and my oldest daughter to work on. If any one can help with the diagram/schematic I would appretiate it. Thanks.
