15.5mm symbol tube manufactured by Burroughs
This is a clear glass symbol tube manurfactured by Burroughs. It can display a plus and a minus sing, the letters "R,M,K", the character AC and an Omega symbol. Maybe this tube was used in a measurement device. The exact type was not determinable, because the print was vanished. Only a Burroughs Logo, the word Nixie, "R07R" and a date code could be identified. I also could not find anything about such a tube in the Burroughs Catalog. The working conditions seem to be the same as the B-8442. If you have any info about this tube, i would be happy to hear about!
