I can't view your picture from where I am, but from the description your lens is early, from 1963-65 as you say.
NKJ is an abbreviation for "Nippon Kogaku Japan", your lens will have this engraving on the name ring inside the filter ring. This engraving is found on Nikon lenses up to about 1970 when NKJ was replaced by "Nikon".
If you really meant to ask if your lens is a compensating model, the answer is yes. You can see this clearly - with the lens focused at infinity and the aperture at f/5.6, look at the aperture blades through the front lens. Now focus the lens all the way out and observe how the aperture blades open, to compensate the the increased extension.
