Manufactured by "Winter Instruments" (Jungingen, Germany) 1970's. This Airspeed Indicator (Fahrtmesser) came from a Schleicher K-8 glider in Austria. Manufacture Number: 43159 (German: Werk-No:) Seen listed for anywhere from US$100-$200. A rare find and nice piece for anyone restoring vintage planes/gliders from the 1960-80's. The instrument was in working order when taken from the plane in the 1990's. It has not been tested or overhauled.
