The felt in larger cases is rarely so intact as yours and this is a huge plus. The key to desirability of any decorative arts or technical equipment is condition, for example, all-original and collector-grade mint, as in camera lenses. Look, for example at the scopes and scientific-measurement pieces in the Zwinger museum, as a baseline. You may be able to nail condition here, by completing the set -- authentically.
A second key to desirability, lots of fun, is identifying what the object is and that is often tough. You may need to go so far as to check factory documents, but it looks to me like you have an item from the golden age of Japanese camera-equipment making and I expect you can readily find a catalog on eBay that mentions your kit, as there are over one-hundred available right now. Identification establishes rarity. It is exceptional to have desirability, even with rarity, when condition is marginal.
To see how this catalog stuff can fill in your knowledge gaps, consider, for example, Nikkor lenses from about the time frame of your kit. To understand makers' intent for old Nikkors, I have assembled Nikon catalogs and a number of old books from the F-mount/MF/film era. For my three 50mm MF f/1.4s, this has helped me understand their development sequence and merits (like the coating improvement on the S.C which followed the three S models) among the nine pre-AF 50mm f/1.4 variants.
Wrt identification, last week, I wrote to a clock museum in France and asked for their help to identify a mantle clock (une pendule).
Before the museum responded my wife realized the maker's signature began with a Q, rather than with a G.
This resulted in finding out that the clock maker made the clock at the Montparnasse metro station, and that he enjoys quite a lot of recognition. This clock episode entailed lots of time, some despair, and finally a sense of winning, while reflecting well on my wife.
The item you have deserves to be protected from oblivion and destruction. For a quick win, consider identifying it exactly, enjoying it, and then donating a complete kit, while possibly securing a valid tax deduction.

These are exceptional pieces and I would bet quite rare.
Look on ebay but they might not be there either.
I would say they have good value but you will need to search the internet.
I found this where this is a $100,000.00 camera and system that was apparently never officially offered for general sale.
