No one has explicitly mentioned the Nikkor-S 50mm f/2 yet, made about 1959-62, first with... eight aperture blades (I think?) and no click stops and then with six blades and clicks, before being replaced with the equivalent but reformulated Nikkor-H. The front element is nearly flat to the naked eye and deeply recessed in the body like an old Helios.
It's the best lens I've ever owned. It came to me on a Nikkorex F, which was a basic but rugged collaboration between Mamiya and Copal on a Nikon contract job. It's contrasty, razor sharp normal with a great vintage color rendition even on consumer color negative. It can be a little cool in temperature but a very light pink infrared filter can make it magically warm... I wouldn't trade it for a Nikkor S f/1.4 or any other Nikkor.
I know of this lens and found about 2 on sale but didn't find any praise on the 'nets for it. Yours is the first praise of the Nikkor-S 50/2.
