The one I have looked at is an Ai ED and believe it is without Internal Focusing ? but I'm not sure. when looking at Serial I think it is with IF... if not ..Is what a disadvantage ?
if it is one of the non-IF you found the one version that is most desirable. The IF lens will stay the same length when changing focus, the older one won't. Based on the serial #, you are looking at an earlier IF lens.
Ai 300/4.5 Nikkor*ED IF MIJ 5+ f22, 7 blades, narrow tripod collar 200001 200050 - 208080 Aug 78 - Dec 81
I have one from the next batch with 9 blades, serial around 220000
But anyone who has the old version should hang on to it:

This lens, one of the first to carry "ED" designation, was only available for a short time in the mid 70's before being replaced with the internal focusing (IF) model. A pity, because the non-IF lens is, or rather was, a truly remarkable performer even by today's standards. It excels even near wide open and the impressive quality holds up well down to f/16
This lens was so well colour-corrected that it lacked the traditional "red dot" for IR photography, because visual and IR focus coincide. However, this by itself doesn't guarantee IR quality (see below)
Focusing isn't...Show more →
he rates the non-IF version a 5, while the IF gets a 4, mostly for CA
I have the IF ED version and honestly, I don't think it's that great of a lens. It handles well and is compact, but it has pretty strong CA. I rarely shoot it wide open. Stopped down it works alright, but my 70-300mm VR consumer zoom kills it in IQ. Obviously, shooting the MF lens is a lot more fun. The colors and contrast on the old lens are more pleasant, too.
