Hello,

My name is Mark and I am from the Netherlands.
I was hoping someone here could help me identify this shell with headstamp that I found on the beach. I think it is a German shell but I don't know it for sure.
Can anyone tell me what the numbers mean? And maybe a gun/canon that it has been used for?

Sorry if I posted this in the wrong forum.

Thanks in advance,

Mark

Those pictures are both the same object. But on the first picture I cleaned it.
