I don't know of any rackmount DVMs by HP that used those
displays; nearly all used Nixie tubes. Might it have been by NLS,
perhaps?
Or General Radio - they used edge-lit displays in some test equipment.
HP had 1-of-10 'thermometer-style' displays in the 50s and early-60s
but started switching to NIXIEs quite early (1959 or earlier).
