I've had this knife for awhile tucked away, and yes then forgotten. But after pulling it out, and having my grandpas friend who makes knives take a look at the picture. (Intending to take them in for him to actually see.) He believed them to be a "Pukko" knife.
I've searched again since on my own in an attempt to find perhaps where it came from time wise, the sheaths seem quite nice and well crafted for the age they seem. But i haven't really seen anything too similar to it. I mean the basic shape yes, but the detain of markings, and the openings in the sides allowing you to see into/through it. Any help would be greatly appreciated.
