I don't want to tell you how to proceed here, it's your gun and you assume all risks.
It would appear though, that you've determined the barrels have not been honed. We're sure there's not a layer of lead in there, right?
If they've been struck down externally is another matter, and while that would be cause for concern if it could be determined by accurate wall thickness measurements, I'd be more concerned with chamber length.
If I found original chambers... I'd be happy. If not... well... tube it or hang it.
The concept of 'hillbilly proofing' is as distasteful to me as actual English style re-proofing. It serves no purpose except to unnecessarily stress the entire gun.
Why destroy something for no reason?
