Unquestionably, the two most collectible serial numbering sequences for Kodiaks that I have seen in my 53 years of involvement with Bear bows would be...
BA which is the 60" maple sight window Kodiaks and the 60" dark Rosewood sight window Kodiaks.
AA which is the 56" 1959 Kodiaks and later the 1960 Kodiaks.
Several of the AA and BA bows have sold for well over $1,000, some for over $1,500 and a few for over $2,000. Many of these bows with specific wood in the sight window are extremely rare, in one case only a single example has surfaced so far and only found as late as 2010. Other extremely rare Kodiaks may surface in the future. One thing I have learned, is that anything could have been made.
Although I have never seen a BH approach the high end sale price of the AA or BA Kodiaks, anything is possible.
