I had no idea so many variations existed. Could you imagine the confusion aliens from space would have in plugging in a shaver or phazer or whatever?
Finding the conductors will be easy because whatever color earth is, will be easily verified with an ohmmeter. Does the transformer primary have four or more leads? You may have options. You might try powering it with a current limited fraction of the voltage you intend to apply and from there you can estimate the turns ratio by measuring the secondary.
Check this WiKI it looks like Japanese air conditioner plug.
