Well i’ve given it a pretty good search and I believe this is probably a theater knife or a fantasy knife. It is not a Remington UMC hunting knife.
Remington has no registered pattern number that matches your pattern number of L1275.
The tang area is unlike what you would see on a Remington.
Also the finger guard is an odd shape than what you might see on a Remington RH knife. There are several other issues with the knife that leads me to believe it is not a Remington production knife.
Nonetheless, you have a decent hunting knife. I do like the blood grove in the blade and the blade appears full. If you hunt this should come in real handy.
