I own one of those actual bows, the model I have I believe it was built in the mid 70s it is 52" AMO. I was told at one time those bows were offered by K Mart back in the day. for $130 bucks jump all over it you won't be dissappointed, if by chance you dont like it look me up I would be interested in it. they built an earlier model that was a 56" AMO version but it was the dogleg version, it was actually called (Black Panther)not as appealing to me. The shorter bows were marked in a double numbered weight(IE: 45/50 40/45 50/55)I personally have been on the hunt for the 50/55lb version.
