I just remembered that they are used in the Leybold 55952 counter as
voltage regulators for the Geiger-tube power supply, but I can't remember
how they glowed even though I think they actually glowed as four distinct
tubes inside the envelope. I restored one of those counters and passed it
on
I just had a look at the datasheet for the tube and it is shown as all
voltage regulators are encased in one envelope, not four separate.

I don't think they're sealed. I think their tips are open to the main
enclosing envelope.

As you say it looks like the tips are open, they certainly aren't melted at
the tip like the four separate ones.
It would be interesting to see the result if the ZZ1030 was checked with a
plasma lamp, that would show if there is neon gas in the envelope or just
in each voltage regulator tube.

Yup - I can buy that...

As I understand it, a getter's primary purpose, within a 'VACUUM TUBE'
is to absorb an remaining 'OXYGEN' from within the envelope. Ira.

Dekatrons use a getter that is flashed and they contain similar gas
mixtures compared with Nixies, as I understand it the getter is there to
absorb impurities from the materials used whereas the mercury is there to
extend the life of the Nixie as it reduces the sputtering.

I don't think it would be counter-productive, see e.g. the XN-1. Neon
and argon are noble gases and hence they almost don't interact with
getter material, as far as I know.

Why would they have a getter? An Hg pill that needs to be vaporized, sure.
But a getter? They are used to remove any stray gas molecules given off by
the glass or internal structures due to heat & time.
Nixies are gassed tubes by definition - a getter would be
counter-productive - even during
> Nixies are not vacuum tubes - they shouldn't have a getter.
Actually, some nixies do have a getter, but it's a different kind of getter
than vacuum tubes use, naturally. Most of the ones with getters use "pill"
getters, often on the back of the anode, and there's normally no "getter flash"
