German WW1 shell case ID needed please!

[AndyD]

Hello,

Please can someone ID this case that I picked up the other day?

It measures 280mm tall and the diameter at the top measures 77mm.

I have attached a pic of the base.

Kind regards,
Andy

75 x 278R, used for different Krupp export fieldguns. With this headstamp (1915, no export stamp) probably used for improvised AA-Guns (belgian or italian 75 mm for example)
