10 mm symbol tube manufactured by RTC
The ZM1263 is a clear glass symbol nixie tube manufactured by RTC. It has a very special spiral symbol, i currently have no info for what the spiral symbol is used or any other information about the tube.
There is another tube, the ZM1262 which has the same symbols.
