New joint pin is the is the preferred method for tightening and putting a gun back on face as far as I am concerned and do so when ever possible .When it is not other methods are used . Problem is that Gunmakers 100 years ago probably did not think that any one would be repairing guns of that age and would have assumed people would have bought new ones by then . I am sure that had you told them this they would have been delighted , then done something about it !
