P. F. DuPont (FOX) ~12 gauge double side by side shotgun by the Philadelphia Gun Company. A costume double shotgun using a
Parker action manufactured for P. F. DuPont.


Probably a Philadelphia Arms frame, with the typical Parker-style sculpting and recessed hinge pin. Researcher may wish to comment on this one.

All in all, very impressive, big $. You need a trusted appraiser for the lot, and plenty of insurance. Unless you inherited these very recently, you are looking at a big tax hit. Depending on your personal financial situation, you may wish to spread out the sales over multiple years.
