Sleeve and have done is the right answer where you come from. Sleeving is not as easily available or as cost effective in the US. Most barrels with major defects are just scrapped. Sleeving will cost more than a grand over here and for that much money you can buy another gun, Sterlingworth in this case. If you look at Gunbroker more than a dozen a week could be bought for about $500.00.
All this for a set of scrap barrels, bought at a gun show. First person decided to part out the gun rather than risk it. Second owner is wanting to save them to make a two barrel set. Are you going to keep searching until you get the answer you want to hear or if the next person you ask, the Fox expert, say go no further then you are done. Lot of effort to save a set of barrels that if in good condition would be worth what $200-400 dollars. 12 ga. barrels are easy to find with out having to rescue this set.
