That looks amazing, how much did that cost you?

Is there that much of a range in brightness of the tubes, or is that a camera artifact of multiplexing the power?
Nice to see something I wouldn't be able to find enough tubes or money to make in action!

here are some pictures of the PCBs and schematics! I've made a driver-pcb for each tube - and two versions: for the IN23 and the B5971 ! So i can mix IN-23 and B5971 tubes ;-D
Each segment gets the current, that i have found in the datasheet for the minimum segment current value minus 10-15 % - for a long lifetime!
The tubes are not multiplexed! I'm using shift register 74HC595 and the SMD variant of the MPSA42. It's all driven by WEMOS D1 Mini (ESP8266). I'm using the NCH6300HV power supply.
Display with IN-23 tubes and B5971 in action:

This is an ingenious approach - I like it. I'm just embarking on a similar journey myself though I'm taking the Smart-Socket approach as I have some experience in using them on B-7971 and ZM1350 etc.
Great work.

first, i wanted to use the smart-socket approach. But that's so much soldering by hand - so i made these SMD drivers boards. For a price ~ 2US-$ for one full SMT-assembled driver-PCB with all parts on it, it was a no-brainer.
