I have been very interested in German 9mm P08 repack labels from WW!! and earlier like the ones below, but have not found any from WW1.
So when I saw the following one, I decided to get it in spite if it being in 9mm BL. The headstamps are mostly “H 8 18” with but one was dated “9 18” and two “4 18” The box was sealed when i got it. My guess is that it is post-WWI packaging of wartime production, but that is only a guess. Other opinions and info appreciated. I know of a number of these boxes in collections, so they aren’t rare.
