Thank you for the compliment. Yes I would agree that your bow would classified as a 1964 model. Actual "born on" dates are unknown as production runs were not in sync with the calander. As mentioned earlier in this thread what would considered a 1965 model would have a 5M as the first two digits in the serial number, a 1966 would have the 6M digits and brown glass. I think the type 3 1963 dogleg Mag would be fine to shoot but none of these bows are going to last forever, so I don't shoot any of my '63 K Mags. I hardly even consider myself the owner of all these bows (aprox 120 Kodiaks, Mags, K Specials) just the caretaker for now. lol
