Kodiak Magnums were only made in the 52 inch length. Grizzlys were made in various lengths, (56"-62"). The 1949 Aluminum Lam Grizzly was Bear Archery's first production bow. All models (bows produced by Bear Archery Co.) previously were handcrafted to order. The little brother to the Bear Kodiak, the Kodiak Magnum was introduced in 1961 and has been in production ever since. An 80# 1968 Kodiak Magnum just ended on e8ay, I believe it sold for a very reasonable price, that is the highest poundage Kodiak Magnum I have ever seen. My personal favorites are the '59 Grizzly and the '64 K Mag.
