Silvers,

I am assuming both possibilities as long as we talk in general terms. I agree that a gunsmith should take a look at the barrels, measure them, then I might know what options I have. It seems that even the measurement of the barrel thickness may be a task not easy to accomplish.

eeb,

The cleaning does not concern me as much as the shooting of the barrels. It is a "junk" gun. I don't have high expectations for a perfectly restored gun, but rather a shooter that I can safely enjoy in the pursue of a grouse or two.
