The K-series was an entirely new design by the Škoda Works company of Czechoslovakia. Although the exact development schedule is unknown, the first contract to deliver 12 artillery pieces was signed with the Kingdom of Yugoslavia in 1928. The howitzers were locally designated as M.28. In October 1929, a Polish delegation also evaluated the design. The contract to deliver 27 artillery pieces to Poland was signed in 1933, with actual deliveries happening circa 1934-1935. At least 14 Škoda 220 mm howitzers were captured by German forces from Poland in September 1939 and re-designated 22 cm Mörser (p). Also, some howitzers were captured in April 1941 from Yugoslavia and re-designated 22 cm Mörser 538(j). Finally, 7 howitzers were captured by the Soviet Union from Poland and were re-used against Finland during the Winter War. The Army of Czechoslovakia had also considered adopting gun, but the plans were abandoned. The fragmentation (anti-personnel) shell for the howitzer was developed in Poland by June 1939, and at least 60 fragmentation shells were produced under German occupation.
