The first NEW factory bow I ever purchased was a 1972 model...which I still have. In my opinion, it was the best looking of the KH's and maybe the best shooter.
BTW, I ordered it from a sporting goods shop in Great Falls, MT, and the owner said he would give me a deal at $50...and no tax.
As TonyW posted, the movie "Deliverance" was very popular and all us kids had to have one of those Bear bows like used in the movie.
