(Webmaster note: Matthias Eifert, Germany, has provided an ID for this tower. This is the Observation Tower on Hohes Gras, just west of Kassel. A Wikipedia article (in German) states that the tower was requisitioned by the US Army after WWII and probably used by Signal Corps units until the early 1950s.
