Dekatron Pendulum - GC10/2P Smallest Dekatron Made

A dekatron pendulum circuit using the GC10/2P. This is the smallest dekatron made by British Ericsson. Its only the size of a typical miniature 7-pin radio tube, like the 12AV6 next to it. Also the same size as the ZM1000 nixie, in the picture, too.
