Yeah, I've got a really old one with the silver
filter ring that's been converted with the Nikon
kit. It's nice and sharp. It's not quite as contrasty
as the later versions with multi-coating, but it's
decent.

Sure. The aperture rings in the Nikon kits had a
second set of aperture numbers for the ADR readout
in the viewfinder, the meter shoe is turned around
backwards (screws towards the objective), the AI
coupling surface has a larger diameter than the rest
of the aperture ring, and there's a little square block
opposite the AI ridge that's supposed to hook up with
that old gizmo that converted the F2 to shutter priority
automatic -- In other words, they look just like the
aperture ring on an original AI lens.
The basement jobs just have a notch cut into the old
aperture ring to index with the camera's AI 'finger'.
If the notch is in the right place, they work.
