Nippon Kogaku objectives wanted.

Have a problem finding shops that sell specific materials? Ask here. Are you looking for microscope parts? Do you have anything to offer for sale? Note: this is not a section for external companies to advertise their products.

Nippon Kogaku objectives wanted.

I'm not sure when Nippon Kogaku switched from marking Nippon Kogaku on the objectives to Nikon but I am looking for a set of Nippon Kogaku objectives. 4 of them if possible but it may have to be one by one. My guess would be that the changeover date was 1952 or 53. The objectives probably just have the bi-convex lens over a triangular prism logo used by Nippon Kogaku since at least the 1930's. That is what is on the matching eyepieces.
