Aviatik was contracted (perhaps with some arm-twisting) to build the Knoller C.II in two contracts, an August 1916 contract for thirty-six Series 36 planes with the 185hp Daimler engine and on September 1916 a further contract for twenty-four Series 136 powered by the 160hp Daimler. Only 18-19 were completed, and none of the Series 136 planes. Like the Knoller B.I before it, the C.II was plagued by failures during flight testing. Against Aviatik's advice, five of the planes were sent to the Eastern Front for combat evaluation in July 1917, where the type was found to be unstable in anything but the calmest of weather. [1]

Lohner was given contracts for sixteen C.IIs with 185hp engines and thirty-two with the 160hp engine, as Series 19 and Series 119 respectively. Productions was delayed to fix problems first found on the Aviatik-built designs. A handful we sent to Flik 50 in November-December 1917 and they were found to be poorly-constructed and useless in combat, and they were quickly withdrawn. [4]

WKF was contracted for twenty-four as Knoller C.II(WKF) Series 81, but only five saw brief service, long after they had reached obsolescence. [5]
