Nomotron Spinner

This is a STC G10/241E Nomotron, in a spinner circuit. Its a cold cathode counter tube, similar to a dekatron. Its can, however, spin in only one direction, and needs 10 times the current of a dekatron. 3.7mA versus 330uA (dekatron). The supply voltage is lower. 330V versus over 400V (dekatron). The glow is viewed thru holes in the anode. The glow locations also have numbers stamped near them.
