shooting a rolling block #2

your last question pushed the 'replies to 10 and locked the topic so I'll start a new one for you ......................................"Ok guys, the shop just called and said the barrel of the rolling block shotgun is too far gone to shoot safely. Any ideas as to where to find a replacement? I've already by to Numrich. No luck there. Please adviseve ........I don't think you'll be able to find and original but a good gunsmith could fit a new barrel to your action. I used to do this with the old martini shotguns, find a boltless shotgun at a gun show for $10 and refit the barrel to the matini action.
