In the 1960's it wasn't a big deal. An old Fox oh hell just another obsolete two barreled gun. I doubt if anyone thought much about it. But how many Fox guns ever went back to Savage to be worked on? I have only seen one that could be documented and it is tastefully roll stamped with the gauge and chamber length on the left barrel and I think they replaced the buttstock and refinished the forend along with re-cutting the checkering.
