Hi all! Regarding to this issue, i'd point out that, according to how Nixies work, the characteristic orange glow of nixies is produced very close to the cathode, and far from the anode. That's the same in the popular IN-12 and all others. http://www.explainthatstuff.com/how-nixie-tubes-work.html
By looking at the INS-1 glow, it seems to me that the orange glow is produced very close to the cup-shaped electrode, that is, the one marked with a dot/arrow. So that one should be the cathode...
