Nikon F 85/1.8

If you want a suitable lens hood for Nikon’s 85mm Nikkor-H f/1.8 lens first made in 1964, several well-regarded internet sources advise a Nikon HN-7, which - like the lens - has been discontinued for some time.
However, there is obviously a predecessor to the HN-7, because I found one on eBay five years ago for £4.99. This hood clearly pre-dates the meticulous Nikon classification system used now.
