Need Help identifying this Shotgun

[Christopher T Case]

I inherited this percussion shotgun, and know almost nothing about it. What I do know is its either a .12 or .16 gauge and has Damascus barrels. what I don't know is when, who, or where it was made. It has no name, serial number, only some proof marks on the under side of the barrels. Can anyone help, Please? the proofs are CH,ML(inside oval), e over lg with a tinny letter that looks like a f or e or b, and two tiny crowns one with an N under it and the other with some mark that can't quite make out but looks like a sideways k or something its very small, there are also three lines or hash marks...? thank you!

Made in Belgium. The LG stamp is Liege. From 1846 to 1924 was when the proof stamp was used.
