I've got an HP 5326B frequency counter <https://www.youtube.com/watch?v=dmG77UuCVJg> I picked up at the TRW swap meet in Los Angeles at least 20 years ago - of course, it was old then (1970's vintage). Even now though, it's astonishingly accurate - it agrees out to +/- one count in the 7th digit with my Fluke frequency reference. I don't hold on to it because of the Nixies, but because it's a damn good piece of test equipment. ~~ Mark Moulding
