I only have a couple of nixie instruments, despite my avatar. One is a Systron Donner counter 1017, with 1291A 50-500MHz frequency converter. Doesn't work and so far I found a manual for the 1017, but nothing for the 1291A converter. I don't suppose anyone has a copy? I'd like to get this working. Mmmm... ring counters.
Yes, it needs a clean. But I don't see much point, unless I can get it working.
This is what my '5' avatar is taken from.
The other is a HP 5326B Timer-counter-dvm. Works, could do with a clean and cal. Ahem... actually, all my multimeters could. There seems to be some disagreement...
