This is a PUMA WHITE HUNTER knife with holder. I believe that the handle is stag antler. This knife was mine about sixty years ago.
Found it while looking through an old trunk. It was never used for anything but somehow got some rust damage on one side. It appears superficial but I do not know what it takes to refinish these.
