Nothing really stands out on it to me as something from a 'name' stocker that I can think of.
I'd guess a hobbiest work.

Set trigger aside,,I only wonder that if it is such, how do you get your finger in behind it to 'set' it. Unless that's not the procedure for this particular one.
It does look like a trigger shoe with the 2 set screws. But it also appears to have a couple of pins thru it.?

I thought the checkering was a bit crude especially the borders and the Fleur de Lis carved outlines.
Not very smooth at all. Enlarging the pics gets you a better look at it.
Borders are not smooth arcs at all. The Fleur's are not at all complementary in shape, are of different sizes and not symmetrical in themselves.

Looks like 3 (or 4?) Fleur's in the forend pattern. But the grip pattern only has one each at the top. None at the bottom by the grip cap.
Seems like it should have been added there also as long as you're in a Fleur mood while checkering.

The stock relief cut under the ejection port is also a bit rough. Rounded to almost match the receiver metal at the rear yet vertical/squared at the front.
Not some things I'd expect on work from a pro or advanced hobbyist..

...but I can be wrong and maybe a big name turned out the stock
