Vertical Gyro Control, US Air Force Type E-4 Autopilot/A-12 Gyrosyn, 656518

$39.50

Here is a Vertical Gyro Control of the Sperry A-12/Gyrosyn Automatic Pilot, known in the US Air Force as the Type E-4 autopilot system during the late 1940's and 1950's. The Sperry part number is 656518 and labeled for a Boeing aircraft specification.  

When electrically powered and in-flight, the gyro produced vertical attitude signals which were amplified and transmitted to the autopilot system and indicators on the flight deck of the aircraft.  

The cover can be removed to reveal the gyro inside. The gyro may been worked on, and all components may not be present.  Would make a very cool display.  See photos.  PDF copies of the A-12 manuals can be provided if desired.
