The Russian Ammunition Encyclopedia shows some nice ammo box labels. They are transcriptions, not reproductions, but still they are interesting.
In page 47 there’s the transcription of what looks like a leaflet put inside of 7,92 SmE German ammunition crates. It seems like a list of bullet drops versus ranges, maybe for firing this ammo over their own troops.
Maybe some of the german natives could translate the label for me… and some other could do the same with the russian caption, of course.
