OK, let us in on who made it?
In reality Totally Unknown.... It does have 'W Richards' on the side plate, but so do a LOT of old Belgian guns......... I doubt very much that 'Wesley' had anything to do with this piece....
It is a 16ga x 40-40 Maynard, near as I can tell, damascus, underlever, Lefaucheaux action, covered in Belgian proofs...
Age??? somewhere near turn of the last century....
Curious, for a 'cheap' gun, the stock has a really nice brass oval inlay, and it has 'cast-off'........ sure fits nice....
And shoots.............
