A pic would help alot,but a 1976 Super K has blue overlays on the riser and blue future wood tips. A 1975 has white overlays on the riser and blue future wood tips. The picture of the Super K in the 1976 catalog has a S#25289. My best bet,it's a 1976. The '76 has a nice slender grip and shoots pretty good too. It was the last SK to come out of Grayling.
