This is an original WW2 German 1944 Dated 20mm Steel Cased Shell Case. This example is in solid condition with some patina and wear to the outer case as shown. This example is dated 1944 on the bottom with the German acceptance stamp on the bottom which is visible. These rounds were most used by the Flak 38 anti aircraft gun. This example was purchased in Normandy but we have no proof this is where it originally came from.
