I have two that might qualify as fowling pieces.
Virginia style smooth rifle in 20 bore by the late GL Jones
And a Centermark French fusil de Chasse I built from a kit. I recently did some custom fitting of a germanic triggerguard and a fancier french sideplate on it.
I’ve busted two nice hogs with the fusil de chasse. One was a big sow at 90 paces. .595 patched RB and 70 grains of FFFG
Edit!!!!!
Oops I forgot! I also have a 20 bore Barnett copy of a typical old Northwest trade fusil. I don’t have a pic of it. But it looks just like all the other NW guns out there. Lock marked "Barnett 1838". I cannot remember the fellows name who built it.
