The rare GC10/A is the world's first production dekatron. The GC10/A sets the form and appearance for all Ericsson counters that were to follow, though it is nearly unique in its use of a helium fill gas instead of neon or hydrogen. The AERE WITCH, virtually the only computer to make use of dekatrons, contained over 800 GC10/A tubes in its memory stores.
