I'm not quit sure were to post this one.
This is the weirdest foreign cartridge box I have seen. It has the marking 9. C. in a rectangle on the back. on the inside of the front flap it has the marking 3 C on the inside of the leather buckle strap, has the marking C 3 (8) and something
I have no idea what this cartridge box is.
Would anybody have a clue
