Help - What is this French Percussion Shotgun?

[MarcCanada]

Hi all,

I just picked up this mysterious, possibly French smoothbore double-barrel shotgun at an Antique show in Montreal for 280 CAD. The seller couldn't identify it, and I'm equally stumped so far.

Here's what I know:
-Lock plates are bear the name "Jean 'd'Courcy"
-The underside of the barrel (right near the breech) is covered in various undecipherable markings, but I I can make out "Ruban Fer" (Iron band), and the "CF"
-The side of the barrel bears "20" and a crown?
-The underside of the stock is carved into a bearded man

Does any know what I might have here?
I found this similar piece on a French auction site: https://www.gazette-drouot.com/lots/15852170-fusil-de-chasse-a-percussion---

Thanks so much!

I don’t know much about French arms but they were master shotgun builders, as that was most of their civilian guns.
If you google fusils today you will get French shotgun firms
The NRA museum at Bass Pro in Springfield Mo has or had Napoleons shotgun
