Empty German 3,7cm PAK Shell Case for the Pak 36 (Panzerabwehrkanone 36) which was a 3.7cm / 37mm caliber German anti-tank gun used during the Second World War. It was the main anti-tank weapon of Wehrmacht Panzerjäger units until 1942. The empty steel shell case is nicely dated 1938 and showing some nice ink markings. The shell case is regrettably rusted to one side, see photos. Nice original example in good used condition!
