Very nice box. Now for the information it gives us which is not instantly evident.
P635 is Hirtenberger ( in Former Austria)
The entire label is in typical German Wehrmacht-style labelling)
Ergo, this ammo was destined for the Official German Military machine.
Question, where were 9mmM SMGs being used in the Wehrmacht?
Solution (?) Units raised in Austria and using quantities of Steyr M34 SMGs ( originally Export Models chambered in 9mmM?) Military Police units ( Feld-Polizei)? Photos exist of Various German units armed with MP34(o), Kaliber unbekannt. (unknown)
Maybe a Military aid or delivery to Hungary…they had MPs in 9mmM ( both Steyrs and others), but that may be spurious, even though Hungary was making the G98/40 rifle for Germany in 1940-41, so it could be a “counter-trade”
The Blue label ( seems to be a “Fur MG” type indication") and the 16 round pack would indicate SMG loading ( 2 packs per 32 round Magazine…very meticulous these Germans.)
No Pistol used a 8 or 16 round loading ( Mauser Brooms (M1908) had a ten round mag).
Any other suggestions?
