personally, I would be looking for a 1960 Kodiak for a vintage shooter, my second choice would be a '59 with the limb tip overlays replaced. The '56 is a double shelf bow and the '58's are going to be a white glass bow which is now big deal. However one note on the '58 Kodiak, they started cutting the string groves deep through the belly glass and into the maple limb laminations. These bows, like the early '59 Kodiaks are prone to delamination. Ask bowdoc how many 1958 and early 1959 Kodiaks he has seen with broken limbs. good luck in your search.
