I just wanted to show three different boxes used for short range rounds NM 8 and NM 127 by the Norwegian military.

I also have some boxes for 7.62 x 63 plastic short range, and they have the same style as the oldest NM 8 box. I can add pictures of this box and the blue plastic rounds if interesting.
