^^^^^^^^^^^^^^^^^^^^ If that is a Weston 1294-series DVM (4.5 digits, TTL,
fits standard 4"*1.75"
industrial instr. panel), I can supply the schematic.
It _is_ 4.5 digits (with individual + and - masked neon bulbs) and
does fit a standard panel opening, but it's an MDPM-3 by Instrument
Displays, Inc., of Haverhill, Massachusetts.
Neat find, as LEDs quickly took over the market for
such panel meters, the
NIXIE tube ones are not common.
They sure did... one day it was analog meters, nearly the next day, it
was LEDs. The window for Nixie tubes was rather small.
I couldn't believe I saw this one on the table for $3.
