Noble,
The second post of this thread shows the difference in the tips of the 1954,1955/56,1957 on the belly side.
The difference between the 55 and 56 Grizzlys is about as insignificant as anything could possible be...
One has water transfer decals, the other has silk screens.
The 1955 & 1956 Kodiaks are also identical, except their cosmetic markings.
Same for 1955 & 1956 Kodiak Specials.
Structurally, these 1955 & 1956 bows are the same.
As collectors, we have this never ending need to put everything in a unique category by year, even when some years are the same, so we invent ways to fill every year, and begin separating bows, by their cosmetic markings.
Frankly, separating the 1955 & 1956 Kodiaks, Kodiak Specials, and Grizzly bows, is fictional, and strictly an invention of us collectors.
Unfortunately, these cosmetic markings were and are easily changed.
