Actually on e*b*a*y*.com there is a 1968 Kodiak Magnum with a bubinga (?) riser which is not laminated.
In a archery shop in Germany there are several KM for sale which were made in 1965 and 1967.
I always thought that the one-piece-riser were dropped from productionline when they started with the laminated riser.
Until when were the non-laminated riser type bows produced?
