^I was going to add to what he said. I would not shoot that gun at all. If anything were to break, it would be a shame. If there are any stress fractures in the barrel, it could be dangerous to shoot.

If it were me, I would clean the gun (not refinish it, just clean it) and put it inside a glass case. And then admire it for who kept it on their side and where they went with it.
