Identify this CRT?

[mbates14]

I picked up an unknown CRT at the local hamvention. For its intended purpose of making a scope clock.

I like this CRT, as its a short neck, kinda small, and probably low HV needed to drive it.

Problem is, its part number is long gone. No idea what it is.

anyone have a clue? it has a funny base. Appears to be electrostatic, and most likely a o-scope tube.
