Guns with new barrels, from the makers you list, and made by them raise a few questions in my mind. Why the new barrel? Was the old barrel out of proof and no longer safe to shoot or was the gun so worn out that the barrels were shot but the action worth enough to invest a set of barrels in? I have seen a few old guns with lots of miles on them that have been rebarreled by the maker. Even new barrels do not turn back the clock so a gun that has been heavily used will still be a very used gun. New barrels or not. So have the gun evaluated just like any other gun.
