Rumpler Eindecker
   Although a pre-war design, as were all Taube types, many Rumpler Taubes saw service use during the early months of the war on reconnaissance duties. Not strictly a true Taube, the machine illustrated above was photographed at Karlsruhe in March 1912, and veteran airman Hellmuth Hirth occupies the rear cockpit, with Lt. Schoeller in front. Engine, 100 h.p. Mercedes D I.
