A big thanks to everyone for all of the suggestions. I now have multiple options.

I was tempted to similarly crack wise but decided against joshing about such a venerable figure in the history of our hobby. 8D

I am tempted to say "madness/insanity" instead of "hobby" but I am also a member of groups for Geiger Counter and Nixie Tube enthusiasts. The former are a generally sober bunch but do occasionally succumb to an opportunity to add a rare and exotic device to their collection and/or upgrade their gammaspec lab to the next level. As for the Nixie (et al) camp...the best way I can put it is to say that some of them must have the most patient, long-suffering and tolerant wives in the world. Watching the price of B-7971s increase exponentially on eBay only seems to increase their lust for yet another six digit clock that can display the time in two dozen different "fonts". Then there's the additional cost of the custom acrylic/aluminum enclosure...  $_$

I'll admit it, I paid $72 recently for an IN-23, my all-time record for a single component. What can I say? It's the only *Nixie* tube that can display most of the Cyrillic alphabet. There are NOS Soviet-era VFDs on eBay that can do a better job but I'm not excited by an indicator technology that's still around (the microwave in our kitchen has a VFD on it). 

Meanwhile, I can relax safe in the knowledge that tomorrow one will go for over $85 and a few months from now they'll be breaking a hundred. As for Nixie clocks, I have a Systron-Donner Time Code Generator/Reader that fits in one rack space and keeps excellent time. A friend of mine gave it to me years ago when he moved to smaller digs. See here:

BTW, if anyone knows how to fix the brittle plastic pushbutton caps I'm all ears. The missing (broken) ones are safely tucked away for the day when a solution comes along.

And I DO have a single 7971—with the socket! Eric Barbour (Metasonix) gave it to me years ago. Only five more to go—NOT.

Finally, I have an ancient Radio Shack kit with Fahnestock clips on it for the 9V battery. It's around here...somewhere.
