x-ray tube was my initial thought too - the first 2 pics. But the 3-rd
and 4-th pic show how long this tube is. Plus the 3 'guns': They really
look like electron guns, with Wehnelt and focusing. Have you seen
cathodes like this on x-ray tube? And three of them? I don't think it
could be a photomultiplier either.
For now, I put it under 'weird contraption, likely experimental'.
Thanks everybody for contributing!

My vote is that this is not designed as a display device, the business
end looks like it has ceramic donuts around it, possibly for heat
dissipation, so it could a source device (high freq signal /
microwave). Could be a Beryllium window at the end so could even be an
X-Ray emitter but the rest of the design does not really fit for that.
It is possibly / quite likely the more i ponder that it is a
scintillation window on the end and the tube itself a photomultiplier
for detecting radiation, they have a similar form factor to that, in
which case that was a superb price.
Looks expensive either way, but a good price on there, though if its
full of hazardous materials (Beryllium) then thats a concern...
Nice find.

Hi Guys,
this CRT-style was recently sold on Ebay:
https://www.ebay.com/itm/115400617434 (I was not the seller nor the
buyer). I have never seen anything like this before. It seems to
have 3
separate guns (RGB?) but the number of pins in the base suggests
almost
no control over the beams. And what is the wine bottle style
topend? I
am totally bamboozled.
Cheers,
Marcin
