Life span of those heavy weight bows (65 +) may also be a little shorter then...oh lets say a 50#er but thats what it was built for..On any 1959 or 1960 Bear Kodiak you want to buy....if it has those little tiny cracks in the corewood just at or just above the fade-outs??? you may want to let that one slide if it's over 50 or so.....One thought on marketing for Bear Archery back then,was about 99% of hunters..Only had deer sized game to hunt.Like Pa.has 450,000 two season hunters.Bear sold tons and tons of 45# draw weight and less...East of the Mississippi or you know what I mean??? But here in Washington we have elk sized game to hunt,and some of use figured we needed a bit heavy bow,ie 45#'s and up..But we only got 15,000 to 20,000 bowhunters(small peace of the market for Bear Archery).You can see where this ones headed...One heck of a lot more whitetail hunters out there then elk hunters here at that time.Look at poor old ABH,he's the only real true to life bowhunter in Alaska.With Moose size game,he will need more then 45#'s.......bowdoc
