Thanks Craig. In all the years that I have been working with phase angle meters or more correctly, in my case, power factor meters I have never seen a moving magnet type, but this could be simply to indicate lagging or leading without any accuracy. Initially my feeling about this object is that it was not meant to be functional and is just a prop but the fact that the dial is marked +/-90 deg. makes me think that is did have a measurement function. I will do a resistance measurement across the leads and if promising then try to remove the compass to investigate further.
