Interesting. My gun also has a leather-covered pad and I happen to have a single-gun case, with an earlier HJ Hussey label, that was owned by H. Max Scheibel of Durham. He was a professor of medicine at UNC.
Does your gun have sleeved barrels? I was at the Southern SxS in April and ran into a fella who sold both guns to Griffin & Howe. Also, there should be an escutcheon on your gun that holds a portrait, complete with improper Latin, yes?
