Full disclosure: I don't know anything about guns. Hoping the good people on this forum can give me some general direction, or more specifics if you know them. This gun was my father's. It hung above the fireplace all my life. I've been told it's a black powder muzzle loading flintlock. It's a little dusty in these photos (no wear), but it seems like it's in decent shape. Didn't find any clues anywhere except what you see in the photos. Any help would be appreciated.
