I measured the transformer this evening and it measures 9 high x 6-1/4
wide x 11 inches deep or long.
There is no visible holes on the top for fixing an ID plate.
It is definitely a plate transformer, probably around 2500 volts each side
of center tap with two separate secondary windings.
Thank you for all you assistance.
