Sometime doing nothing to a gun is the right answer. Fix what is needed to make it safe and functional but not to restore it. The plus is that you can use it without worry because it has that well worn look already. Guns have character from all their bumps and bruises. I have a couple very well worn guns that I just keep as they came to me. A hundred years of wear is sometimes a sign of good service and respect.
My late uncle had a .410 Creacent double he used for decades. Even after he could well afford any gun he wanted he used that gun most of the time. So when it came to me I decided if it was good enough for him this way I'd keep it the same to remember him as he was. A good, hard working man who never complained about his life or troubles.
