Good evening. A good friend of mine told me about this forum and recommended I reach out to see if anyone recognizes or could help identify this old shotgun. It belongs to a widow and neither of us have any idea what it really is. It is an old double barrel black powder percussion shotgun chambered in what I believe is .410. The inside diameter of the bore measures right about ½” and the barrels are 36 ½”. The side plates are engraved and the right one is stamped “WARRANTED”. The word “LONDON” is stamped between the barrels 2” from the chamber. The trigger guard, hammers and top of the action are engraved.The stock has brass designs of a hunter with dog and a deer on the left side and a squirrel and bird on the right. The overall length is 53”. I have numerous pictures but don't want to dump them all on the site unless asked to. I would really appreciate any assistance. Chris.
