X-Ray tube.

Old X-ray tube from the navy xray dept I used to run in the 80s.
23cm long. Weighs about 1.5 kg.
Rotating copper heat sink with the tungsten target.
See, I've always been into glass stuff.
I've had this in a drawer for over 20 years.
It's a toshiba tube.
An interesting curiosity.
Thanks for looking.
