1. The 2t22A I removed from a 45' pole in Lowry Air base.
Touched today, when I alligned Tootie's rotor so both upper and lower rotors blocked their ports.
2. A CD siren we found on a roof of a building in Yantai, China, 8-2006.
When I moved it's rotor either direction, it always stopped blocking the stator ports - preventing animals and snow from entering the unscreened stator.
Felt like there was a magnet attracting the rotor to it's parked position.
