I have a brass case for German 21 cm howizer model 1910. Diameter 219mm, length 232mm, rim 236mm. In literature I have read that Germany had these guns in WW1 only 192 pcs. In 1917 Sweden bought 12 pcs slightly modified guns called model 1917. Finland bought from Sweden in 1940 4 guns with 800 rounds of ammo.
I can't see in literature that Germany had used this gun any longer during WW2.
Was the same case used also in other guns, or are these pretty rare? I have seen a few brass cases, made in 1916 and 1917 by Polte and Karlsruhe.
