No markings on this one, and definitely one for the collectors as it has a few flaws...
Note a small chip in the glass and some burn marks from use. All the digits light up at 300V with 12K resistance except 5 and 6... you can see some glow at the rear of the tube on those digits, so not sure what's going on there....
Anyway, PM me if interested.. If anyone knows what type of nixie this is, I'm all ears!
Cheers,
Nick
