Xavier,
It sounds like you're describing a 1958 Kodiak. Does this bow have a leather grip? If so, it's definately a 1958. Fred Bear decided to build the Kodiak with white glass in 1958 to commemorate his first "bow killed" Polar Bear. He shot prior Polars but they had to be dispatched with a gun at the last moment. They were only made this way one year. If it's in really nice condition it's a real prize and a great shooting bow. If I'm wrong about the reason for the white glass, someone please chime in. Enjoy,
