Shotshell headstamp ID please

Can anybody give me some direction on these two headstamps?
I believe the red one is from Bosnia.
The other one I have no idea.

Regards rené

René, very nice shotshells!

The green one was made between 1945 and 1948 by Vojnotehnički zavod in Valjevo, Yugoslavia (pre-Krušik).



thank you very much.
This makes it even more nice.
Being made only for three years!
