Starting around 1962, the new lenses that Nikon introduced were in millimeters instead of centimeters, but cm-marked lenses continued to be produced until about 1967.
This resulted in a hodgepodge of mm and cm marked lenses with many minor inconsistencies. There are quite a few rare or unusual variations of lenses from this period. Because of this I refer to this period as Nikon's Weird Years.
I especialy like the early mm lens that carry over features typically associated with cm marked lenses such as patent pending markings, being marked only in feet or meters, silver front rings, ribbed aperture rings.
The 10.5cm / 105mm f/2.5 P (silver front) is interesting because it swapped between cm and mm and between being marked only in feet or meters and having both feet and meters multiple times. I think a screenshot of Roland Vink's amazing Photosynthesis site does the best job of conveying the inconsistancies of this time period.
The 50mm f/1.4 S is interesting because it swapped between ribbed and scalloped aperture rings and being marked only in feet or meters multiple times.
