I also have some off these. Even the Tank ones-with metal backings.Just gotta find them樂.I'd love too contribute some $$$,towards boards/parts,if thats any help..

I've been running some SPICE simulations on potential candidates for the HV 
supply, and I'm close to having something I can run from my function 
generator. I've done enough basic testing on one display with sinusoidal 
and triangular waveforms running thru a power transformer to confirm the 
display works. I'll put this onto a small PCB and hopefully test it out in 
the next few months. I'm aiming for operating around 1Khz, and the 
iron-core power transformer I'm using right now seems fine up to around 
5Khz before it starts to poop-out.

I havn't finalized how to drive the individual segments; most likely I will 
use small triacs. I've used opto-triacs many times before, so I'll probably 
stick with them unless I find "regular" triacs for a lot cheaper. My only 
concern is the leakage current of the triacs might cause the segments to 
glow, as they only need a few uA. That's another experiment I need to do 
after I have the power supply nailed down.

You might remember this thread from 
2018: https://groups.google.com/g/neonixie-l/c/UJczdz85J8o where I included 
a Russian book on these displays and also pointed out a Russian website 
plus Mark Moulding wrote about his experiences.
