The tube is a hydrogen thyratron. It is used in many high powered Radar transmitters.

think of it as a very large very high voltage very high
current scr. Absolutely useless for audio unless you
intend on using 4 of them as a primary switcher for an
audio amplifier in the 100kw range.

and if I'm seeing things correctly, is the tube "double-walled"?

Yup I have one just like it, except yours is in a bit better shape, probably a newer build. I just have mine set up to glow, with a 200w load across it.
