This strange device is an Ericsson GCA10G 'direct drive' glow transfer counting tube, a dekatron specially designed to be coupled to a Nixie display tube without any intermediate hardware. The GCA10G has a series of ten supplemental anodes arranged equidistantly around the inside of the tube, one for each output cathode. Nixie tube cathodes are connected to these anodes; as the glow transfer passes by a supplemental anode, the flow of current will jump between it and the primary anode, causing the appropriate character in the Nixie tube to illuminate.
The GCA10G is an early counting-only variant of Ericcson direct drive technology, and lacks many refinements, such as the finned primary anode and curved secondary anodes seen on the GSA10G selector from the same family. The GCA10G's lack of selector output cuts the pins on the base down to 18, compared to the GSA10G's modified 27 pin base with an extra pin in the center of the socket.
