Superb take Ram; yes it is 4 x 1.6 = f/ 6.4.
When I had in two moments 2 copies of the 500/4P I had no luck, since they were not good copies, mostly wide open and at f/5.6. Your copy looks like a winner.

Shucks, wish it was ALL mirrorless cameras shooting Nikon MF.
There are several of these more general groups at flickr, even some like "mirrorless cmeras + legacy lenses", but 99% of images are taken with other than Nikkor lenses. This is the reason I was more specific for this group.
