8x Extremely Rare Numerik Ussr Indicators (Lightguide Display, Edge-lit Display)

  
I'm pleased to offer: Vintage Numerik Indicators (Lightguide Display, Edge-lit Display). Quantity: 8 pieces in this lot. This display has plates with holes drilled in them in the shape of numbers.

The plates are bent back to lightbulbs on the back of the display. When a bulb is lit, the light travels down the plate and lights up the holes. It can be used in the readouts of counters, computers, digital voltmeters, annunciators, and indicator boards for various systems where digital indication is desired. Each item is meticulously packaged to guarantee its safe arrival.
