Nikon AF Nikkor 80-200mm 2.8 D Lens Two-Ring Version Not Working

Serial Number: 792343

It comes with Lens Hood, Front Cap.

It shows signs of use.

The lens is mostly clean, with a few dust specks inside.

Autofocus works but occasionally it gets stuck. Manual focus doesn’t work.
The zoom works but between 135mm and 200mm it feels like the rubber ring must be grabbed very firmly for the zoom to move – it looks like a problem just with the rubber grip and not the zoom itself.
