ARMY AIR FORCES SERIES C1 AUTO PILOT VERTICLE FLIGHT GYRO TYPE G-1021-A. The C-1 Autopilot system was used extensively in WW2-era bomber aircraft of the US Army Air Forces, including the B-17 Flying Fortress, the Consolidated B-24 Liberator and the B-29 Superfortress. The control panel would typically be installed at the pedestal between the pilot and co-pilot.
