All About Pocket Knives

Can anyone in the knife community tell me who might have made this fine knife
Knife is 5 inches closed with beautiful black Buffalo horn flat handles and flat bolsters.
Blade is carbon steel and3/16 thick.
I would appreciate any help as to who made this knife.
I believe it is called a large fish knife.
Thank you

Sorry I can’t help you with maker ID. Unusual to see a blade like that in that frame. Most of that pattern I’ve seen have a long slim clip blade. Perhaps someone replaced the original with that blade (the pivot pin looks suspicious to me). Can you provide a picture with the blade closed lying on its side, and one looking down into the blade well (also with blade closed)? That won’t identify the maker but could help determine whether it’s the original blade.

I can't help on ID either - It looks like a cross between a folding hunter and a fish knife -

I think that would be an Ulster but I'm not positive on that. I've seen a very early Ulster with that very same handle but the blade had a long pull and a slightly narrower shape. Is that blade pin steel? If so as Ken mentioned the blade may have been replaced.

PS- OK, found another pic I had with a crescent nick in that frame. They must have done both pulls at different times. The long pull was on an older Ulster-Ellenville stamped knife. Here's a shot of the crescent pull version:
Still questioning the blade in your knife though as it appears to be saber ground, which was a blade more frequently found in the old cokebottle knives.
