Vlim beat me to it, as have been busy all day. I believe that your box is similar to a nice condition box I have, that is full. The label is mostly light blue, with only white ends, and all print is in black. It is a 16-round box. Mine holds cartridges of the German Type mE with lacquered-steel case, brass primer with black primer seal, GMCS RN bullet, and headstamp “dou.-St+ 5 45” (although of course yours could have been a different lot).
The box appears to be Slovak. Perhaps from the language and abbreviations someone can tell us if the language is Czech or Slovak. It is a post-war box from 1946. If I have time tomorrow I will email you photos of all sides of the box and you can post them on the Forum. In the interim, I will type the label out for you and others. Please note that the caliber I have typed is NOT a mistake. That’s what the box says:
VZ 08(N) SE ZEL. JADEM
Pl. B. XII 1946 PRACH (0,8-0 ? wal
PARTIE 23 N 0,38 S? 1944/2
There were some punctuation marks over letters that I did not know how to reproduce on this Forum. Question marks within the label content indicates that I believe some character was there, but that it has been obliterated by wear since it is right on top of where the lid tucks into the box.
Of course, neither I nor anyone else can say that my label is identical to what yours was, based on two characters left on yours. There could have been other labels from PS before or after this one. I would be surprised if they did not quickly correct the printing error showing the caliber as “7.92” rather than 9mm, for example.
As I said, I will send you photos so you can see that I have reproduced my box accurately, and that it really exists.
