That's good enough, Juha !
In part due to the MG42's fantastic rate of fire, the extractor left every casing with a very distinctive dent on ejection.
Looking down on it, the cartridge mouth looks like a 'D' with the straight side bent in. Actually surviving examples are quite scarce as the weapon almost always fired steel-cased ammo so all you usually find is a small pile of rust.
Anyhow, over to Finland for the next question....
