You're correct. Those are vacuum fluorescent display tubes. I tend to use "nixie tube" for all similar display types, but they're completely different technologies.

Closely related anyway

I like the old fashioned hand drawn PCB layout!

Interesting circuit board. I would expect the front of the nixie tubes to face away from the board. For example, a frequency counter that I used in the Navy (state of the art at the time) used nixie tubes. They displayed out the front of the box, and the circuit board extended behind them. What is the device in this picture used for?
