German 20mm Oerlikon

[Luuk9319]

I have this German stamped 20mm oerlikon cartridge. Who can help me identifying the headstamps? I have never seen the z in a cirkel before. Is it German produced?

 

[Luuk9319]

Heard it could be possibly Czech? It also looks like there is another stamp under the eagle.

 

[15 inch]

The mark under the eagle is a lion rampant so Bulgarian? I have also seen the Z on Czech 8mm. I don't know about the BV - that might stand for the case material supplier? A German foundry Bochumer Verein used BV - just a thought.

Maybe ammo made by Czech factory for a Bulgarian order?

I show a Czech 15mm Besa headstamp with the similar Z in a circle just for interest.

Hey Luuk9319,

What specific Oerlikon case is it - eg 20x72 RB, 20x80 RB, etc?

 

[Luuk9319]

It's a 20x110RB

Example of a symbol in a "Z" ring (without barrel bore)It could be the production: Zbrojovka Brno, Vsetín plant.
Among others, it produced 20x110 RB cartridges both before and during the war ..
