Airspeed Indicator Fahrtmesser Fl 22231, 80 – 750 km/h Luftwaffe

Here is an original WWII-era Airspeed Indicator Fahrtmesser Fl 22231, indicating speeds from 80 – 750 km/h, as used in aircraft of the German Luftwaffe, such as the fighters Messerschmitt Bf 109, Bf 110, and bombers Junkers Ju 87, Ju 88, and Dornier Do 217.

This indicator shows Fl 22231 embossed on its dial, and Fl 22230 on its rear case. The dial is clearly of the Fl 22231, so it is possible that the rear housing was replaced using that from a Fl 22230 as they would have been interchangeable.
