Hi Jack,
Just a wild, wild guess!
Silversmith A deals in silver manufactered by himself and also in secondhand silver, he takes in a fine piece made by his main competitor, silvermith B, but he does not want his customers to note the quality of his rivals workmanship, perhaps he feels uncomfortable applying his own mark over that of his rival and so he uses a worn out punch, (they could be file marks and the lozenge shape of French silversmiths would be similar) to make the original producer anonymous.
I have noticed similar treatment on items of Irish silver.
Like I said, only a guess.
Regards Trev.
