OG3 (ОГ3)
Dekatron counting tube
(Version with Metal base)
Made by
Анод
, Дятьково, Россия (Anode, Dyatkovo, Russia)
Bi-directional single-pulse decimal counting tube.
Argon filled.
You'll notice a dark coating of some sort, inside the glass envelope on the top on all the Russian dekatrons, also on that OG-3 Dekatrons.
That coating is NOT a sign that the tube is used, but an intentional part of the manufacturing process.
The following pictures show the tube spinning.
Of course, only one of the cathodes is glowing, but the shutter speed of the camera generates different pictures:
a high shutter speed of the camera:
a medium shutter speed of the camera:
a low shutter speed of the camera:

colour not like the OG3!
