[Scorch]

16 ga from Belgium, no doubt about it. Has some signs of having aspired to being a fairly high-quality shotgun at some point in its life. The crowns on the barrels may be intended to infer some sort of association with the royal house, I don't know. The barrels and the barrel lug are brazed, judging from the green oxidation being lifted by the oils on the steel. Decorative tooling like that on the bottom of the lug is usually found on the more expensive guns, but any decorative tooling on good guns is usually of a lot higher quality of workmanship than what you see on your gun. It would be interesting to take a look at it.

Take it to a good gunsmith for a once-over. Just remember, there was a reason it was in your father's junk pile. Parts it needed may be unavailable, or it may be unsafe to fire for any number of reasons. Or it may have just needed some work that he never got around to doing.
