Original Kochgeschirr 31 with (maybe) a battle damage.
I found it myself as a little kid near Koblenz. It is a real late war battle example that was left over by the fleeing german troops.
Non matching maker (Lid is marked with “ESB41”, the can itself with “ZPStZ 42”)
The soldier scribed a few things in it.
It has something on the lid that looks like a bullet hole.
