Chuck,
I have read that in Jorge's book and I've researched archived threads here at Tradgang and over on the Wall.
I have no doubt the various stampings were done for a reason and meant something to Bear Archery and their retail distributors, but, all I have ever seen for an explanation, was, speculation, a hunch, or heresay.
I own or have owned a few 22 stamped Bear bows, a few with star stamps, and a 61 Kodiak with the serial number removed with no stamp, and none of them were "severely defected", appeared to be "refurbished" or otherwise damaged.
I can buy in to the theory that stamped bows were returned items and either resold at a discounted price or donated to civic groups to promote archery, but just can't see Bear Archery "refinishing" or "refurbishing" bows. I mean, heck, Bear Archery retooled 3 times in 1961 to produce 3 variations of the '63 Kodiak Magnum. That tells my simple, and sometimes tunnel visioned brain that Fred wanted new shiny unflawed models out there on the landscape to promote next year's offerings. Kinda like the Detroit Auto Manufacturers mentality of, sell new shiny models early and keep improving them to stay ahead of competition.
As nice as the wood is on the 1962 KMag in the pics above, there is a long fairly deep and fairly straight scratch right down the middle of the overlays on the front side of the sight window. Looks kinda like something you'd do, if you weren't careful, with a utility knife while opening a cardboard box with a very nice bow inside. It could be pretty easily sanded out and resprayed. Perhaps, it instead got a star stamp and sold at a reduced price in the "bargain cave" at Bear Archery. I don't know, anyone's guess is as good as mine.
