A friend of a friend posted these pictures on Twitter of a component she found in her basement -- it apparently had one end labeled 'P' and one end labeled 'N', but no other markings...
My instinct is a GM tube, since I've seen one here recently... but I figured other people might enjoy playing a game of 'identify that component'! My conjecture is that the "tube of crap" inside may well have been a getter, if it was to live in a vacuum otherwise.
joshua, still finishing up his SSTC, and will post about it here eventually, but wanted to break his many-year silent streak first...

Well, I'm utterly baffled. If there was a Mystery Component Of The Year award, I think you would win it.
The substance in the "tube of crap" may well be a dessicant called Drierite, a mixture of calcium sulfate and cobalt chloride. See if it turns pink when exposed to moisture.

Looks like I was *square on* wrong.
"Finally found the missing clue to the basement tube mystery: the sealed glass tube isn't empty. It contains a few drops of mercury. The device is a tilt-sensor. Upright, the mercury completes the circuit at the base of the tube. Tilted, the mercury flows and breaks it. Testing shows the light goes out when it's tilted past 90 degrees. As to what it was used for on a ship...you've got me."
