The lack of barrel markings has me wondering if the barrels are not original WR, or, have been buffed mercilessly. The barrels are off-face, and the extension/doll's head appears to be poorly fitted. I also wonder if the patchbox wouldn't be on a breechloader, unless converted from a muzzleloader. The gun is not mine. I thought it might be an interesting addition to my gun locker, but, there are too many questionable things, especially the barrels.

The gun in question is a typical Westley Richards conversion from muzzle loader or pinfire. They often did beautiful work on the conversions.
