It does not look Mexican or South American made to me at all.
I would say it is a WWII era theater made knife, looks like many similar I have owned

Wullie: Nice Piece you got there.
Did you guys know that the Nambu 14 was rumored to be where Bill Ruger came up with the idea for the blow back action on his Late 1940's patent on this one.
WWII Randall Model 1 Springfield Fighter. The knife has a 7 1/2" carbon blade that is marked "Randall Made / Spfld.Mass.". The sheath is original to the knife. The stone is also original, still retaining its paper label. There were aprox 1100 of these made during WWII..

I've got that site bookmarked, just in case I ever manage to run across a knife such as your Randall!
