SIXSKB-Sounds like a nice gun. If it has survived this long in the condition you describe, I suggest you let a GOOD, experianced 'smith do any more disassembly. It's real easy to wreck screws and wood to metal fit if you are not used to that sort of work. Maybe you know what you are doing but, what's the rush? There is someone out there to take that gun to for cleaning and evaluation. You just need to find him.
