I have aquired an interesting looking "vacuum tube" that I am unfamiliar
with. I was able to research the name/numbers on it and came up with the
term "transmitting tube". I still don't know what it is for, but am
fascinated by it. Can anyone tell me what it's for? Here is the link to one
of the pics:

You can see several images of this thingy at the root:

Truth is, I'm not familiar with these items, but it looked cool to
photograph. I do hope to find out some more about it and maybe even see if
it still works.

Thanks for the assistance.
