This is a two seater training and performance glider of wooden construction in a cantilever mid-wing configuration.
In 1935, at the German DSF works, engineer Hans Jacob carried out the design of the two seater training and performance glider with an open cockpit. The glider was named "Kranich" (crane). The second series , known as the "Kranich II" and built at the Schweyer works in Ludwigshafen had already enclosed cockpit, air brakes and improved pilot's seat. These successful gliders were built also in Czechoslovakia, Sweden, Spain and after the war in Yugoslavia.
The IS-C "Żuraw" (crane) is the Polish version of the German "Kranich II", recreated at the Gliding Institute after the Second World War, based on the survived examples. The works on the completion of the serial production documentation were led by engineers Józef Niespał and Antoni Kokot. The Polish serial gliders first flew on 22nd April 1952. They were produced at the No. 4 Sport Aviation Equipment Works in Gdańsk. In 1952 - 1953, 51 examples of the "Żuraw" were built. They were used at the aeroclubs until the half of the 1960s.
The displayed at the museum , the SP-1213 "Żuraw" flew at the Gliwice Aeroclub.
