Does anyone have any magical way to make a serial number appear? All I've done so far is rubbed with gun oil. But as it is my level of precision is, I think it may contain a "5". Probably doesn't really matter, but it would be helpful to know if it was an early or late gun because it appears there were a few differences. Anyway, given it's a family gun, in rough shape and won't ever be shot, what do folks think I should do with it insofar as work? Affecting value isn't really a concern, since these don't seem to be worth much, and I wouldn't ever sell it anyway. Right now I'm thinking clean and oil it, get it functional and call it good. But part of me wonders about going a little further maybe doing a little refinishing? But it's hard to imagine it turning out to be much given the starting point. Any thoughts?
