My cold cathode (using XC18) all-valve clock only works in the light,
the rings fail if the clock is left in the dark. So that clock is now a
demo one only. But it did run without fault if I kept it in the light.
I've bought enough Z700U trigger tubes to build another trigger tube
clock. These have a priming electrode so should not fail in the dark.
Here's a manual that shows how to count and how to drive nixies with
them. The project is on the shelf at the moment while I play with other
things...

They do appear on ebay from time to time. I bought mine from
galinar...@gmail.com
But I don't know if he has any stock now.

Mike, what about 'normal' dekatron life ?
Do you, or any other member here, have any experience with long running
dekatron or trigger tube counters ?
Or should I consider a dekatron/cold cathode trigger clock only as a demo
object?
