These are from before my time.
Two of them, mail order many years ago.
Hint to use you squint through slit on black plastic end
If I knew what they were I might be able to answer your question.
It's an extinction meter (exposure meter). There is one for sale on Ebay.
Technology sure has come a long way.
You are correct! Cannot imagine accuracy

But, you can test the accuracy easily enough. Fun project for a lazy day.

Yea, they are roll film holders. The numbers showing are visible in a small opening and shot the shot number you are taking. The multiple riws/colums of numbers are there because not all cameras put the window to view the shot number in the same place. The numbers are not the same in all of the rows/columns because different cameras used the same film but created different size negatives. For example one camera may produce 2 1/4 by 2 1/4 square negatives and a dufferent brand/model camera may be creating 2 1/4 x 3 1/4 negatives. I also had a 35mm camera that took split frame shots, taking 2 shots in the same space as a single normal 35mm shot so a 36 exposure roll would give you 72 exposures on the split frame camera.
I don't have to manage using those. They are not called "extinction meters" because they are extinct- but they have been for a long time. They did work in most daylight situations, in a manner speaking.
When I was a kid, just after the Pelapenician Wars
the older amateur photographer in my family would hand me down their old gear. After messing around with those "meters", I found the old f/16 bright sun trick and the instruction sheets packed with the film were more accurate. My next gift was a Weston meter, the one that was shaped like a bar of Octagon Laundry Soap. That meter actually worked well once I learned how to make reflected light readings. Then came a Weston Master I, and a Norwood Director- the one with a swivel head that Sekonic later replicated.
Interesting.
I have never seen one.
It looks more like some kind of roll film than a light meter.
Here's a YouTube link to what has to be a major light meter collection:

Whoooooooh hoo .... no way ! Look carefully.
The numbering sequence tells you what they are used for (although zilch about *how* to use them). Likewise the word "Weston" tells you that it calculates exposure.
If youve ever "peeled" and souped rollfilm I must assume that it was waaaaay long ago.

If that "Kalaidescope" is branded "SEI", its very useful, accurate, and $$$ valuable.
I remember having one of those and an older Zeiss 35mm my uncle gave to me. I was about 10 - 11.

No, he did not. Yes, it was my mother's brother.
