They made them in the mid 70's. They are not listed in any Bear catalogs because they were made for K-mart and I believe coast-to-coast stores. Mostly modeled after K-mags. I thought they only came in 52" like the the K-mags, but a friend of mine had one that was 56". Bear did'nt really "claim" them for lack of a better term. The other strange thing about them is they were weighted with a 5 lb range. Like 40-45 lb or 45-50 lb. Bear also built one for Sears that was another anomoly, cant remember the exact name of that one right now it was something like "hawk". Similar to the Panther, but it was a strange duck too.
