Yes, it is. Back when I collected in Michigan I was told by several folks that Fred felt there was a place for white glass on some hunting bows...maybe he was thinking about polar bears, or who knows what. Didn't make sense to me: how many bowhunters went after polar bears in the 50s? But, Fred did make some not-so-good decisions(the Playboy ads, for one, did not play well with Henrietta! I'll bet ol' Fred paid for that one many times over!!!) But, I'll go out on a limb and say if the '58 Kodiak had been made with rosewood and brown, black, or grey glass, we'd all be saying it was the best Bear ever!
If I had a choice between a '59 and a '58, I'd take a '58 every time!
