Dannegger

   The primitive Dannegger Taube is something of an enigma. It was out of date and obsolete when it appeared in Hamburg in 1914. The landing gear is obviously over designed and there is no fin or rudder. It is thought that the national markings are spurious as there is no record of the German military purchasing a Dannegger Taube nor of one being impressed. The insignia may have been applied by the company on their own initiative.
