Those lenghthwise grooves in the shotgun tube set are really odd. Remnants of some sort of rifling, maybe straight rifling? Or signs of shoddy manufacturing or whatever mistreatment?
Mixed with pitting and all sorts of scratches, what can one say?
But since there seems to be choke boring, I'd say these barrels were intended for shot, not for some kind of bullet.
