>What the Dickens is it?
It's a coil that causes a small vane off center when there is current flow thru the coil. There also the a permanent magnet used to center the vane and a lamp to cast a shadow as the vane moves off center. It a little like a meter movement.
> Is there a way to test it?
Yes there are at least two thing to test. Coil resistance should but less than 1400 ohms. The other is the vane blow on it gently should move freely.

Vol 1-50 admiring the old set and trying to
