In the white Repro
 

Anyone know the person(s) responsible for the engraving and the stockwork on this shotgun?

The stockwork looks like factory Repro work. Don't know about the engraving. One poster seems to be familiar with this gun.

I thought the same thing. Thank you for your input.

The $64,000 question is, why would anyone with any knowledge remove the hinge pin? It was not engraved, at least not the side we see. Certainly not the easiest thing to do but maybe easier on a new gun. But could it have been done at the factory? I remember the guns in the white that were to be engraved, but the reversal makes little sense.
