I vaguely remember reading that Mr. Baumann (?) died and that was the
end of the turns counters.  It is a great shame as they provided an
excellent solution for amps builders.  I hope someone else has happier
information.  I suspect that there is still a pretty good market for
those dials!  Baumann ran a small photo ad in QST almost every month, so
he must have been selling a few!

Yes, this was the beauty of the dials.  Just attach them to the front
panel and use a shaft and coupler to your vac variables or rotary L.
Neat and economical.  I used a pair on a 3-1000Z amp and found them very
easy to work with.

Hope you find a source.  If you do, please share it with the rest of us!
