This instrument measured the turn angle and side-slip of the aircraft, and was connected by a SEPARATE dedicated battery, as opposed to the main electrics. It was located in the Do335 and Me262B cockpit or main instrument panel and acted as a back-up Turn/Slip in case there was any issues with the main system (or electrics). It could also be plugged into a secondary socket for emergency use.
Made of aluminum and steel, this VERY RARE late instrument is a SUPERB example and dates around 1944. Though the battery supply is not included, it is otherwise 100% complete! This was removed from an aircraft by a US veteran. The Fl. number is complete on the data plate, clearly indicating Fl. 22413. It retains 95% of it’s original finish, and features no rust or damage! I have indicated it’s location in the last photo (Do335 Instrument Panel). A SUPERB item, perfect for any collector, display, or restoration project!
