I have to agree with RR. The punch marks on the table only tell what was at one time, not what the gun has been subjected to since. A reproof of each and every piece would be the optimum fix, but that's a different road to follow. What I've always wondered about is some of the same gun buyers that recoil in fear of a shotgun that has had it's chambers and/or forceing cones lenghtened that put it out of the security blanket of proof in their minds, but seem to in no way be bothered by other repairs. Re-pinning of the hook or welding on the same to fix off face actions, striking and rebluing barrels, annealing and then recase coloring actions, tightening lockup to put the lever to the right, etc. Some would instantly require reproof, others depending on the degree of work. Look at the alterations & restorations done to bolt rifles with the welding and other gunsmithing operations and no one bats an eye or even mentions(re)proof. Judge each piece alone, including any alterations or work done to it, as to wether it was performed properly and safely.
