Original German WWII Luftwaffe Aircraft External Temperature Gauge with Intact Plug by Siemens & Halske AG - Fl. 20349

Original Item. Only One Available. In aviation, information about the outside air temperature is extremely important for the pilot to take appropriate measures in good time. This electric "remote thermometer" shows the temperature of the outside air. It consists of the actual thermometer (Fl. 20341), a temperature-sensitive resistance wire, the display device and the power source for the measuring current (board battery). The thermometer consists of a winding surrounded by a metal protective cover.

The gauge is marked with the logo of Siemens & Halske AG of Berlin, the Electronics company that developed the FF33 Field Telephone, and still exists today. There are faded markings around the circumference of the gauge with manufacture information. The back of the gauge actually retains the piece that plugs into it, but only this piece. A very interesting addition that shows how the metal bracket locks in place at the back of the plug. 

This is a lovely piece that could have been fitted into a number of German aircraft during the war. Comes ready for further research and display.
