Blackhawk, you're right that newer models had the same bushings / raised coins. But, from 73 on the coloration of the S.K.'s changed. The 73 and 74 were all dark w/red stripes. The 75 and 76 had blue stripes. The 72 was the last one with the rosewood caps and dark handle. At least thats what my catalogs show. If you have a dark handle w/rosewood caps and a raised coin, you most likely have a 72 model S.K.
