damper actuator

Description

I worked for Staefa Control System which became part of Siemens, for twenty years - The best work years of my life. This has been on a shelf in my garage and is used in a dirty box. Tested, when 120VAC is applied, it runs to the end of rotation, when the power is off, it spring returns to the original position. It is only missing the "U" bolt and nuts that grip the damper shaft.
