Which brings me to another one of my boat anchors - GR-1192B freq.
counter which worked fine for 20 years just stopped counting.

Nixie tubes. Ah... nostalgia. I've got several boxes with Nixie
tubes (HP5248M, HP5246L, and some home made junk). I think I paid
more for the printed manuals than for the counters and downconverters.
The usual problem with ancient hardware are the electrolytic
cazapitors. If you have an ESR meter, test them to see if they have
"dried out". If everything looks like it's working (display lights up
and digits change when thrashing the buttons), then it might be the
time base oscillator or dividers. Try an external time base
oscillator in case the crystal has quit.

I am
trying to find a manual on the Manual exchange group but so far no
reply. No BAMA record, either. I know the new counters are cheap and
tenth in size, but the neon display tubes look so nice...

General Radio morphed into GenRad and was bought by Teradyne. The
test equipment division went to IET Labs:

The have a few manuals online:

but not the GR1192B. Send them email as I'm sure they have a printed
copy in the archives that only needs to be scanned. Maybe just the
schematic and block diagram.

I make it a habit of buying or downloading the manual for literally
every piece of test equipment that I use. I find myself repairing the
old equipment all too often:

Note: It's a lab, not a museum.

Just got mail from K7ITM offering to supply the Eico coil info. Thanks
for the Heath data.

Cool. One question. Is the frequency range of the Eico the same as
the Heathkit ranges that I listed? I'm curious.
