WRONG WRONG WRONG. I have one!! It was the main nav compass for a B17.
I purchased mine from one of the surplus places about 5 years ago.
There was an article several years ago in one or the electronics mags about
how to play with these. I believe it was in the hardware hackers column.

I have not managed to make my WWII flux gate work, for several reasons.
 1) lack of doumentation.
 2) lack of the electronic section, I have the flux gate and the indicator.
 3) Its a three phase system, all new systems are two phase.
    I believe they used a three phase system, because all they had for
    indicators were syncro motors.
