The 1963-65 KS looked very similar to me, but if serial # starts with a "5", then it's probably a 63-64. The "experts" will come along soon to verify.
Values of the Specials are not up to what the Kodiaks bring, but still they are nice looking and nice shooting bows. Based up on assumption it's in excellent shape, I would think that $200-300 would be a range of value.
