This one is Belgian.

I should show you the maker's mark on the barrels to see if you recognise it.

I have been in contact with an English man who collects bayonets, he's shown me a few variants of the proper Belgian sporting bayonet for this gun.
Very expensive though! Sporting bayonets seem to be rare, and the bayonet for this rifle would likely get something in the neighborhood of $2000 - $3000 (USD)
I will likely find a similar short hunting sword from the era and cast new metal handle bits and fashion the grip stocks out of horn. The 'right stuff' is also longer than what I want to use as a hunting knife or bayonet, I'll proabally keep the blade length of what I make for this rifle under 14"

I think you've seen this image before, but this is the first target I printed with that rifle. Those two hits down on the lower left corner are the first right and left barrel hits --right next to each other-- at 50 yards.

As much as I want to do more work on the loads, I think this would be just fine for pigs under the cover of jungle or tight woods!
