[AMRadio] what is this old power supply?

I've found a power supply, green front panel, rackmount, sockets for four 
VT-145 tubes.

label #1:

POWER UNIT TYPE 5008/9
REF NO 110K/525
A*M  NR 2080

(the * is a symbol of a crown)


label #2:

SIGNAL CORPS U.S. ARMY
POWER SUPPLY PANEL PN-12A

It looks like high and low B+, and filament supplies for something. On the 
rear chassis face is a big ceramic terminal for the high voltage and a long 
terminal strip of about 20 terminals for everything else.

Has 2 chokes A27094
transformer A27090
transformer A103004

Anyone know what this is part of, and where a wiring diagram might be had?

It is weighty.

Thanks,
Patrick
