The type of objectives that you have are the most common type produced in Japan over a long period: achromats. Yours look to either Kyowa or Meiji but similar type objectives produced by Carton, Fuji, Olympus or Nippon Kogaku would all perform similarly, although some might be slightly superior for various reasons. Kyowa made objectives for many customers for many years, as well as under their own name and their optical quality is excellent. I have a Kyowa microscope with objectives virtually identical to yours, only marked Kyowa. They perform beautifully for what they are; achromats.
For photographic purposes, those conventional achromats are unsuitable because they exhibit too much lateral ca, curvature of field and sometimes even flare or coma. That's why with older photo systems compensating eyepieces were recommended and the image captured was only a small central part of the total field. As plan objectives came along, those problems of lateral ca and others, became less and one was able to capture a larger total, flat field, with better edge definition. Better yet would be plan fluorite or planapo objectives but one loses some working distance increasingly with higher N.A., so samples need to be more precise and the higher magnification fluorites and apochromats often , can not be focused at all with cheaper prepared slides due to excessive slide thickness.
I would be looking for a short tube set of plan objectives. They will be unlikely to provide better central image performance but the periphery of the field will be better for photos. Very few companies offered plan objectives in the J.I.S. short tube format. Almost all you would see, would be either Olympus or Nikon. I haven't seen short tube Meiji plan objectives, all I have seen were made after they converted to D.I.N. 160mm but they continued to make optics for science supply houses and the like, after that; Cenco, NorthWest etc. You could improve the microscope with a set of J.I.S. plan objectives but they are hard to find and seldom at a good price.
Other option would be to sell it as is and get a used trinocular system with plan objectives. Since you have an AO 10 head, you could probably land an AO 10 frame really cheaply. AO planachro objectives are really easy to find. That's a pretty easy microscope to get up to a quality functional photo system, with superior optics.
Apochronaut, is the best advice I have ever received. In few words you have shown my options, thank you for your time, I appreciate it.
