This sort of multi-role aircraft built by the Luft-Fahrzeug-Gesellschaft G.m.b.H was a truly advanced aircraft by the time of its first flight in 1915. Nicknamed the “Walfisch” (Whale) due to its deep all-wooden fuselage which filled the vertical gap between its two wing panels, the C.II displayed remarkable low drag and was both fast and sturdy. The model entered service in the spring of 1916 where it proved to have demanding in handling but also a success in its various operational duties, recon and escort mainly. Over four hundred were produced.
Pretty impressive artwork/cutaway appeared in the American Modeler magazine Sep. 1962 issue. Regrettably this one doesn’t display the humorous curtains some of them carried on their fuselage windows.
