 The most successful of AGO's wartime aircraft was the C.IV of 1916, of which 70 examples were built, but which proved unpopular with its pilots.In 1916, Gustav Otto opened a new plant in Munich under the name Bayerische Flugzeugwerke, and another in Oschersleben (with Josef Schnittisser) again named AGO, this time for "Aktiengesellschaft Gustav Otto".The Oschersleben plant was used to manufacture components for other manufacturers' aircraft until the end of the war.
