EDO-AIRE MITCHELL CENTURY I Automatic Flight System,  their AK-475 eligible for the Mooney: M-20C, M20E,M20F, M20G and M20J  14vdc Mooney Single Engine Aircraft.   STC SA3049SW-D.    System was acquired from an avionics shop that was selling seven years of equipment, that they had removed or upgraded.     They represented the equipment in an "as removed" condition.    I have no way to test.  There appears to be all major required components and some installation hardware.  The major components are:

1 each 52D75-4 14v  s/n 10724 E  Turn Coordinator and Controls for wings level, roll command and Hi/Lo sens for Omni Tracker ( Tracker was an option) 
1 each 1C508-1-523R s/n 6582A Roll Primary Servo with flywheel
1 each 1A526 s/n 13916 Interface box

Could be a nice system of spares, or the Turn Coordinator or maybe to get an Autopilot in your Mooney at an excellent price.  This equipment was likely sold in the 70's.   Please bid accordingly and consult an approved shop for proper installation requirements.  Thanks for bidding and see our feedback to bid in confidence.
