Halberstadt C.V (DFW) 4205/18

German aircraft manufacturers were required to provide aircraft with a factory data plate as well as an army data plate. The army data plate is pictured above. The two data plates were mounted on each side of the fuselage, usually near the nose, as well as elsewhere on the aircraft.  This data plate is most likely from a DFW-built Halberstadt C.V (DFW) C.4205/18.
