Thank you everyone for your much appreciated advice. When I measured the current with the meter the nixie did just faintly glow at the bottom of the tube, so I have connectivity. I'm thinking it's "cheap meter syndrome". It was only a $40 meter. Now I know that my technique is OK I can approach this stuff with a bit more confidence.
Thank you again.
