Started at 300 VDC for initial testing... The high voltage to help with poisoned elements or getting ignition if low gas pressure.
Now running 200 V with 12k series resistor and the tube self limits at 5.3 mA on the "8" digit. The small glowing spot at the base for digit "6" with ~2 mA tube current and the supply running at the programmed 200 V across the tube strongly suggests an open at the base between the pin and digit structure. Will peak in with a stereo microscope later tonight. OK... How about driving with a fast edge and using a counter or fast scope to make a Time Domain Reflectometer measurement for the length of the wire?
