Well with the green glass the 59, 60 and 66 are out. Serial number is wrong for a 65, 62's and 63's are listed as grey, but to some eyes look green. 63 is the dog leg very easy to recognize, 64 has weight forward riser but they are not laminated like the 1965 on up thought the Super Kodiaks.
Now though you will find a lot of people calling Kodiak Hunters, Kodiaks too, but they aren't quite the same bow and should never sell for more than $100 to $150 although lately they do.
I am betting 63 or 64.. 63 $250-$300. A 64 at that weight you might be looking at $450-$500, due to their reputation as hard shooters. Now if it is a 61, with out a star stamp and few to no stress cracks, you could be looking in the $500 range too.
Dan... a couple more reasons.. Nostalgia aka history as well as fit and finish second to none. Sure don't disagree with your other 2 reasons either.
