I'm guessing it's an old waveguide t/r switch gas discharge thing.

I'd suggest that the pinched tube was used to first evacuate the unit and/or then to insert a gas mixture into it. It could then become a conductive element. (It may also have served during glass blowing?) No idea what it looks inside, though -- no pictures. I have only wild guesses right now.

Yup, that's my guess, too.
Jon
No it is not a waveguide gas discharge T/R switch. I have seen those and this does not match (no waveguide flanges).
?-)
Could be a disc-seal diode. Maybe even triode (I can't make out how many connections).
The venerable Rohde & Schwarz Polyskop SWOB 1 used a similar-looking triode in its cavity oscillator.

-- Since what seems to be a tubulation is crimped, it may have been used to suck down the tube and then to backfill it with???
It doesn't seem to have filament connections, although it could be a diode. I'm guessing it's a waveguide thing and the top connection is the keep-alive. Maybe a high-current gas discharge triggered spark-gap sort of thing?
I should have ohm'd things and such.
Yes. I was cleaning up my junk cubby downstairs and found it in a dusty box. I must have picked it up a a flea market long ago.
I'll do that next week.
Ditto. It's about an inch in diameter.
Yeah, it could be some sort of high current closing switch, and the
