This shotgun has been offered to me because the owner knows I collect old 1800's single shot rifles, and had mentioned the name Carlos Gove to him. The shotgun is a side by side muzzleloader, and the sideplates are marked "C. Gove" and the top rib is marked "Carlos Gove Denver Col". Next to that the marking "Stub Twist" on the rib.
No idea as to who the maker might be, or whether it was simply sold from Gove's Denver shop, or if he bought barrels and locks, and assembled it in his shop?
Wondering if anybody might be able to identify the shotgun, or parts used on it from these images I got?
