This is a cardridge case for the famous german "7,7 cm Feldkanone 96" from the first World War (77x230R).

67% Cu means, that the brass consists of 67 percent copper.
Manufactured in October 1917 in the Cartridge-Factory Karlsruhe.

Thanks Stefan!

It was a big help for me. Is it possible, this case was the base when Germans developed the 7,5 cm KwK case (7,5x234R)? It is my suppose.
