The Ehrhardt 7.5 cm Model 1901 was a field gun designed and built by the German company Rheinische Metallwaren- und Maschinenfabrik and sold to Norway in 1901. It remained the main field artillery gun of the Norwegian Army until the German invasion of Norway in 1940. The Germans impressed the surviving guns and used them in Norway for the duration of the Second World War. They equipped German units in Norway and were used as coastal artillery guns; a number were even modified for use as anti-tank guns. A dozen guns were transferred by the Norwegian government to Finland during the Winter War and were used by them during the Continuation War as well.
