Need help with indentifiying german Ammunition

[Marcel Stern]

Hello my friends, i recently visited the beach and found a bullet casing in the water on which the front end is a little bit damaged, but the writings on the bottom are still readable
If someone knows where this bullet is from i would greatly appreciate it, i searched on google and it looked most familiar to a MK103 but i am not quiet sure about that.



the writing says: 21m at the top, on the right it says: P414 which is the ammo factory that it got produced at, on the left it says: 37 and at the bottom it has a eagle and small numbers which i cant make out to well but it should be: Wa4231
it has not been fired yet

the front is damaged so i dont think this is gonna be useful but here: 135mm

and the bottom is 26mm wide

That sounds like it`s a German 20x138b flak round....Pete.

Yeah looks like its German 20mm flak: 20x138B "Long Solothurn" 20 MM cannon cartridges

Thank's everyone for helping

is this common or is it a more kind of rare casing?

They are rather rare to find with metal detecting in my experience. One mostly finds the steel ones and they are often very far gone. But if you go to military expo's you should have the brass ones for a few euro's.
