German 21cm Howizer 1910

[Tmine35]

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.

There seem to be a number of the cases in the U.S.

Cases are very common in The Netherlands and Belgium.

So, I assume that the same case was used for other guns as well?

As far as I know only for that gun and the modernized versions. The cases have been used in WW2 as well, even steel cases exist both from WW1 and WW2. But those are really rare. The common ones are the WW1 dated brass cases like the one you show.
