E1T / CV5106 indicator
Essentially a very small CRT, the E1T emits a ribbon-shaped electron beam which is guided to the fluorescent screen. In operation, the beam is moved one step at a time to the left by 'D' and moves to the next slot in G4. At each slot, electrons will also pass through the corresponding slot in A2 and on to the screen. When the beam reaches the far left it strikes A1 which can be used to reset the beam and thus the count via external circuitry.
Base, and two shots of the internal structure.
Hard to see without opening the device, but held to the light, three of the 10 slots can be seen.
