Peter - I had forgotten these boxes, and did not notice it because all of these are top-label up in drawers. Here is a picture of the marking on this-style box.
I am sure everyone can figure it out, but in Peter’s picture, the reference to the guns is “voor Stenguns” referring to the British machine carbine Sten. I mention it only because the “S” is obscured.
The identical boxes as shown by Peter and I occur also loaded with cartridges of the same headstamp, but with black primer seal and GMCS-jacketed bullet, as well as with the red seal, CNCS type shown by Peter.
