A few more additions at: https://cameragossip.github.io/nikon-lens-patents.html

  • 35-70mm f2.8 AIS

Really? The only entry I see is Nikon AI Zoom-Nikkor 35-70mm f/2.8S.
And the patent next to it (US 4806000A) is all 28.8-83.3mm f/3.5-4.0 examples.

  • 105mm f2.8 micro AIS

This looks like Tale 72 (which I think you wrongly identify as the AF-D lens).
I have this already as a different (perhaps identical) patent.

Nikon AI AF Micro-Nikkor 105mm f/2.8S

OK, yours looks like the AI-S that's not AF.
Looking for an authoritative diagram.

  • 600mm f4 FL-E

Nikon AF-S Nikkor 600mm f/4E FL ED VR

  • 800mm f5.6 FL-E

Nikon AF-S Nikkor 800mm f/5.6E FL ED VR
