I rescued this from the waste container after our yearly flea-market. I had seen it, but of course nobody wanted it. I guess it came together with the 1961 Tektronix scope that we also had (which we actually sold for 10 Euro's to a guy who first asked: what is that ? Then I explained and he said, Oh cool, I'll buy it LOL...no idea where it will end though...)
Anyway, back to this CRT.
It is a rond tube, face is flat. The phosphor is yellow. It's from 1969 and for US navy use. So, this was meant to go into a radar on a navy vessel one day.....makes you wonder how it ended up here. By the way, that oscilloscope had a "Government property" label on it too, dated 1984, so they used that scope for a pretty damn long time
The phosphor on radar scopes have an "after glow", I guess most of us have seen old-fashioned radar, else check this out:

Anyway, that afterglow makes it useless for TV use, but it might be pretty damn interesting to see how it would do on Asteroids or Lunar Lander !
The bonus was that there was even a yoke in the box
An alternative use for this would be building a CRT clock, something like this:
