ZM1043S
30mm symbol tube manufactured by Tesla
The ZM1043S is a special character indicator tube with clear glass. The character height of 30mm makes this tube a companion to numerical indicators like the ZM1040. Its a rare tube, beause it was produced in less numbers as the numerical indicators. I assume these tubes were used in applications where positions are envolved (X-Y-Z axis) or in measurement instruments. There is also a model with red coating, the ZM1041S.
