We have a acquired a very limited number of these rare and sought after panels. They are new old stock. The C-1 Auto Pilot (along with our PDI gauge) was a component of the Norden bombsight system as installed on the B-17 Flying Fortress, B-24 Liberator, B-29 Superfortress and other WW II bombers. These units measure 8" square by 3 1/2" deep, and display very well. Made in the USA.
Note: For C-1 Autopilot operating manual, see our part number LIT-0116, for PDI Gauge, see our listing INS-0107
