Ok folks, I've had this knife for a long time. I picked it up about 15 years ago at a yard sale. It's an old trapper with a tang stamp from the 1940(some say '45)-1964 era, short bolster on the rear and here's the curious part, LEATHER handle scales! Has anyone ever seen a case folder with leather scales? I'm not talking stacked washers, I mean one solid piece of leather pinned to the liner. Was this maybe a dealer sample that never made it to production? One off custom made by an employee? Any info would be appreciated.
