72mm ring?
Looks the same as mine, I used a 72mm to 52mm.
I think the same could be done with 80mm squares, but would nee dot use a very large ring, and several rings maybe to get down to whatever size is needed for the lens.

Yes, that would work. I tired a 40mmx40mm in a 58mm ring, that worked, but not for 52mm lens.
I used the 72mm for 50mmx50mm, that works for 52mm lens threads perfect.
Circles are much more fun. :)

Yes, that is like mine. :)
I have a friend in Moscow that does UV, IR, UVIVF, UVIIRF, VIIRF, etc... she is also an art forensics expert. Thus how I have all of my Russian filters. She is very smart.
Perhaps you and Dmitry and her could all get together sometimes and shoot some pics together...? You all live in Moscow, I think. I wish I could do something like that here.

It is a good thing for Americans and Russians to know each other.

Here is my test of a Hoya X1 (green filter), which I believe is the closest filter equivalent to the Russian ЖЗС-9 filter (closer than Hoya X0, see Hoya graph, previous page).
My same regular testscape, with ever changing lighting.

Yes, the colors are very similar to ЖЗС-9. And there seems to be a little more color with Hoya X1.

gloomy weather. ЖЗС-9

This may also be equivalent to my YG-2x

dabateman, I forgot to write. Not "may" but for sure it is. YG-2x is is a designation of ЖЗС-9 for an export. ЖЗС-9 is brand of glass
