This knife was originally my great uncle Jim's. I do not know if he carried this during his service in WWII or not.
The knife has a 4.875" long blade, OAL = 9.25". Shallow clipped edge and a fuller. It is stamped on one side with a straight line Remington and the DuPont oval. The other side is devoid of all stamped marking.
The sheath appears to be the original one when it was issued.

I had a horrible time identifying this, but finally I received some solid information. This information was based on D.Y. Grimm's book (p.25), “Identification Guide To Remington Sheath Knives 1925-1940”.

An “original” RH-44 introduced in 1938 and production ended in 1938.
Offering was during the DuPont era from 1933-1940
The overall length should be 9 3/8” with the blade length at 5” steel, same blade as on the RH-34
The handle material is engraved hard black rubber with nickel silver discs and colored fiber spacers
The half guard is of nickel silver.
It has an aluminum butt cap with countersunk brass nut.

Based on the description that was provided to me, my blade is about 1/8" short. Not a completely full blade, but close. Considering that is is about 84 years old, that is not too bad when taking into consideration that it was used and not just put away.

I tried to learn more about my uncle Jim, but it seems that everyone that knew anything at all of him has now passed away.

This might not be a true military 'combat' knife, but I am including it in this album because it is possible that it was used for that purpose in WWII.
