Autopilot Control Panel for C-1 Autopilot System

The C-1 Autopilot system was used extensively in WWII-era bomber aircraft of the US Army Air Forces, including the Boeing B-17 Flying Fortress, the Consolidated B-24 Liberator, and the Boeing B-29 Superfortress.

This module, one of 10 modules in the system, is the control panel, typically installed at the pedestal between the pilot and co-pilot. The other modules are three servo units (aileron, rudder, elevator), a directional stabilizer, the vertical flight gyro, amplifier, inverter, and junction box, with a later generation adding the rate gyro and rate gyro adapter unit in Boeing B-50 bombers.  Was also installed with a "formation stick" controller in some aircraft. 

This example is in good condition for its age. All of the knobs turn and toggles flip.
