Default How to identify an unknown transformer.

Hi all,
I have a Western Electric transformer but I know nothing about it.
A search of the model number on Google turned up nothing.
I remember when Google used to be useful.

Is there any way to measure and tell the input voltage of the primary winding?
As it came out of a piece of US air force equipment I am worried it may be a 120V transformer so dont want to hook it up to Australian mains till I am sure.
Unfortunately there was no input voltage marked on the equipment either. But since it was a valve unit I figure at least one of the secondaries will be 6.3 volts.
