In the past I have read on this form, that both the Kodiak Hunters and the Kodiak Magnums had the upper silk screens on the back of the limbs in 1971, and they were moved to the belly side for 1972. I could assume that the Grizzlys did the same thing, but I'm not sure. I have two Grizzlys, 58", black glass, shedua; one has the upper silk screens on the belly; one on the back. All the Grizzlys that I have seen that were from 1964 to 1970, had the upper silk screens on the back. All that I have seen from 1973 to 1978 had them on the belly. Wondered if they made the change between 1971 and 1972?
