What is it?

Vibrator inverter

That was my first thought too, but the wires come out the bit in the top and go straight to what looks to be a socket at the bottom.

Shooting blanks guy's. Hint was that boB is disqualified because in his area of expertise he would have nailed it promptly. Unfair advantage....

Keep shooting!

Is there a lense on the face down end?

If so, my W.A.G. is a light or sensor to sense an object in the area.

Otr not

I sort of thought it looks like a device to remote mount a tube. Like you unplug it in the middle and then plug it into the tube socket and plug the tube into it

That's how it's installed....but not for remote use/purpose......

It isn't a tube rejuvenator is it?

Going to give Doug this one. CRT Booster etc. to increase the heater voltage on dim picture tubes. 

[boB]

Yep.  Installed a lot of those because of my dad was a TV repairman for many years.

My uncle (Dad's brother) used to re-build picture tubes and I used to replace them in the customer's home and in the shop.  Robin did that a bunch too.  Only had one implode in the home that I know of  !

My uncle Loyal would replace the gun assembly. Diffusion pump and flash the getter and all that.

First one to say "Waveform" gets to stand in the corner! All day... So, "what is it" that the waveform specifically represents?

TJ,  you SURE I'm not excluded from this one ? I had to check my text twice !

This MIGHT be one of your trick questions and if so might be from some strange welder of yours.

BUT it looks very reminiscent of a television (PAL or NTSC ?) vertical interval or, if not to scale, a color burst on the left side followed by a horizontal sync tip and then a line of video followed by more sync and video but I don't see more color bursts.

Or maybe it is teletext ?

You are correct on the "type" of waveform, video. But the "trick" part is what does it represent? It is a legitimate waveform, and getting closer as you read this. 

[boB]

Well, since I don't see color bursts on the back porches of the horizontal lines on the right, it looks
to me like a single line of repeating info or white to  black to white (or moire pattern, etc) on the left followed by video lines which I can't tell what they are except for some random-ish luminance information for the start of a displayed screen.

Might be the first few lines (less equalizing pulses) of the vertical interval of  a screen.

If I had some reference for time, it might (or might not) help

Well, the waveform is much closer than it was when I last posted...that's a valid time reference.
