Mmm yes, quite right. At the absolute minimum striking voltage the formation of the glow will be slow (potentially many seconds), ambient light dependent and these days pretty uncertain as the tube will not likely conform to specs after such long storage (we know that GS10D and similar tubes degrade in storage - what Martin is referring to as outgassing). When testing GS10D I run them up to 625V (transiently) before deciding whether or not they're dead or dying.
I doubt the loose base is the issue. Most dekatrons with loose bases just have a bit of failure in the cement that holds the base shell onto the bottom of the tube - it's not directly involved in the integrity of the glass envelope per se. Nothing that a judicious drop of glue can't stabilise... I'd suggest debugging the circuit on one of the tubes that Mike designed it for, and then adapting it to your GS10D.
