Jim,
Funny, just yesterday I was looking at the design of a laboratory cesium
beam standard from 1963. Sorry, there's no divide-by-5 example in there.
But the attached images show the 108x multiplier (8.5 MHz to 9180 MHz).
Sure enough, spot the 12AX7 and 6J6 tubes in use...

Yeah, but I think those are multipliers, not dividers.
So then, what shall we call it. PICDIV draws from the PIC. Next thing
from TAPR, catering to the retropunk style, will be a TUBEDIV or EJDIV
(Eccles-Jordan homage) - what better to drive your nixie (or stacked
neon bulb) display than a 19" rack full of modules.
I'm sure if one looks at pictures from WW 2 era, there's plenty of this
around.
If I didn't have many other projects going, that might be a cool one.
Lots of folks have binary clocks on their desks at work, but they're LED
and solid state. A few have Nixie clocks, but solid state driven.
