An AAA weapon that was used only on ships built for the Germans during World War II, but the ships that survived the war were then commissioned into the Netherlands Navy. This gun was used on a Bofors designed triaxial mount for the twin mountings. These were criticized by the Germans as being overloaded as the cross-level axis carried not only most of the shield but also the very heavy casing for the dredger hoists.
Apparently built with a loose barrel, jacket and removable breech ring and had a vertical sliding breech-block. May have been a derivative of the Bofors Model 1924C which was manufactured under license by Wilton-Fijenoord.
