Percussion Double-barrel hammer shotgun #1

[MMA10mm]

I was recently gifted two muzzleloading double-barreled shotguns. I have been working on cleaning up the first one. It has no makers markings or any other exterior markings, other than cheap-looking scroll engraving. It has hammers, and the barrels are not Damascus/twist, but I’m not sure they’re steel either. They are covered in light rust, but no deep pits. The best markings for identification are under the two barrels, where the forend covers them up. There is a series of 4 proof stamps on each barrel. The one I can make out is “13” which I assume stands for tge proof pressure of 13 tons. The other proofs look British to me, but they could be French, as the decorative work is kind of fine and pointy; not very British looking to my eye. I’m attaching photos.

The ramrod is missing of course. . There is a horrendous crack in the wrist of the stock and it has a very old repair:View attachment IMG_1459.jpeg
