What is it? I think I found the answer....PICS added to original post

Possibly from a plane, it is some type of imaging device. Heated sleeve.
Any ideas?
ETA: Second pic
ETA2: an infrared camera!? Or just a "vidicon" tube (camera) without infrared capabilities?
Don't matter...I know if the sell out over the weekend the first guess was correct! Either way, it looks really cool (pics are bad)
Now who wants to help in getting it to work (have a few more)

An ICCD perhaps?
I think you're on the right track :) It does look like some kind of photocathode at one end -

Been digging around at the shed have you? 
David I have asked you about those before and I'm still curious as to what they are..

It MIGHT be a photomultiplier tube.
I don't understand the coil around it, photomultipliers don't need or use one.
A vidicon tube with magnetic deflection? Don't think so because the coil would be x/y axis kinda thing I think.
There is the heater tape with regulator, magnetic shielding [the nickel alloy sheath], looks like the base is potted and there's a few resistors in there it looks like and might be the voltage divider string.
Why are all the connections brought out? Usually not done for a plain jane PM tube.
Is there a number on it? More detail of the internal elements would shed more 'light'...
It might be some sort of speciality radiation detector that usually has a scintillation emitter [crystal], optically coupled to the front. The coil may be some means to control electron multiplication and the multiple leads could be to measure different particle energies.
Bunch of wild guesses I like to make.
Maybe the coil is to demagnetize the electrodes inside after an EMP event.
That many turns of fine wire imply a high impedence/low frequency response, of the coil...
Final thought for tonight, if a PM tube, maybe the coil is to hold the electron bundles in a tight path [focus] between dynodes to allow for a compact tube?
Break it open and see if there are sort of regularly spaced 'element's inside along it's length.
If it's a vidicon tube, there will be a distinctive electron gun with a filament [low resistance] indirectly heating a cathode close to the base and additional coil windings under the visible one.
Nice wire, save it for a perimeter trip.

Looks expensive

Streak tube version of vidicon?
