Forgot to add another comment I had after reading the patent... The tube appears to use a similar approach to the National Union tubes, where any individual electrode could be used as an anode or a cathode, depending on what glowing shape the user wanted to display. It's been stated before that difficulty in driving the NU tubes using the circuitry of the day might have contributed to their design being superseded by the simpler to use Burroughs nixie. And indeed perhaps something similar played here - looking through all my collection of Ericsson materials, I can find no evidence they ever sold this tube - the first ETL nixies seem to be the GR2G, GR4G, GR10G etc of the mid-late 1950s, which are more conventional in operation / design.
