Gyro Horizon, Electrical, Luftwaffe Fl.22410-1 Wendehorizont
This is a fine example of the electrical Fl.22410-1 Wendehorizont, or Gyro Horizon, as used in aircraft of the German Luftwaffe during WWII. Likely made by Askania. According to various reference sources on the internet, this instrument was used in aircraft such as the Bf109G, Do335, FW190 A5-6, and Me262. See photo of Bf109G cockpit.
The knurled rim around the glass lens can be rotated, which in turn cages or releases the gyro. There is a floating-ball bank indicator at the bottom of the lens.
Measures approx 4 inches diameter and 8 inches deep. It is in exceptional condition given its age.
