Your knife is Western as owned by Coleman, leather, pattern 66, made 1984. In the Walden years, Schrade made the 147L, which looks about the same, but without the patented bifurcated tang construction of the Western. Both companies also made Delrin-handled versions. Before Coleman bought Western there were some bone-handled versions, and the Black Beauties, which had alternating black and aluminum discs stacked on the tang. They started the pattern just before WWII, and there were even a few stag and various celluloid versions. Schrade made one for Sears with a red and white striped handle. There were experiments with Wonda Edge serrations. Etc., etc., etc. One of the all-time classic hunting knife blade grinds. The Schrade 147 was dropped and in 1973 the 49r series began with the 497L and 497S. The very earliest of these used up some 147 blades.
