What would you like to know?  All the data is right there that you need.  Maybe you would like to know to what piece of equipment it was from?  That would be hard to say unless someone can recognize it as being from some piece of gear they have seen before.  But from the current rating on the secondary HV, it doesn't seem to be good for any amount of power.

With about 50% efficiency, that plate voltage at that ma would output around 230 watts. That's 100% transistor and FET territory these days.

We are Coulomb of Borg. Resistance is futile. Voltage, on the other hand, has potential.

Somehow I cannot imagine a 30 lb transformer being rated at only 150ma at 3000 volt.

Its also unusual that it has three separate 6.3VAC windings. I expect it was used in some special application (medical perhaps) rather than a normal transmitter or amp.
