wow.like I said I have no idea of what all these bows are.I know I have 2 of the mamba's also, my dad and friends were fanatics about bow hunting in the late 50's thru the 70's.I believe my Bear take down is one of the originals, I know for a fact it came out of Grayling, every year dad made the family go there so he could get his new one...I really appreciate you making me aware of this web site, I'll let my dad's friends know about this site and try to post more information on what bows and equipment we have. I'm sure they have interest in getting rid of some of this stuff since they are in their 70's and haven't pulled these bows in over 15-20 years
