You might look for plate supplies for high power radio transmitters, 
say based on some form of beam tube (klystron, for instance).  you're 
a little low on power for where 3 phase and that high a voltage would 
be attractive, but you never know.

Peter Dahl transformers ( a big maker of custom plate transformers in 
Texas) probably has exactly what you want, but it will be muy pricey 
as brand new.  However, looking through their catalog of replacement 
transformers might give you a clue as to what kind of transmitters to look for.

Lots of radio and TV stations are dumping their tube transmitters in 
favor of solid state these days.

You'd also likely find some nice inductors.
