Today I received a box with three Nikkor lenses. The box has no markings. It probably had four at one point, but one is missing, sadly. Two are rehoused Bronica lenses (Nikkor-P 75/2.8 and Nikkor-Q 135/3.5), but the other is a APO-Nikkor 150/9, on which I cannot find any information.
Sadly one of the aperture blades has gone wrong and the lens won't open up to f9, and only close down from f22 to f90. It also has a waterhouse slot, that can be closed with a lever.
All three are rehoused in large barrels and have filter adapters to 62mm. The barrels and filter adapters are all marked "For use to [insert lens specifics]" The barrels have large threads to mount, and mount in the wooden box. All three have Nippon Kogaku Tokyo lens caps, coincidentally all three are different (Two are one-sided spring caps, but one has the pin on the left, the other on the right. The third is a two-sided spring cap.)
What were they used for, and what kind of lens is the APO-Nikkor 150mm?
