This is an extremely interesting box as John says above. Within the last year I posted in the European bulletin asking about a box for these rounds.
The label has a German Army format, but it uses the code “N” and on the box clearly states these were RWS loads, but in 1933 all RWS autopistol ammunition was loaded by Geco. The load has the typical Geco look. Since 1924 post German military production was done by Polte and used the P code. This was because only Polte was authorized by the Allied Control Commission to produce 9mm P08 ammunition. During 1924, other German factories were producing restricted ammunition, in the case of P08 ammunition it was the Cassel Arsenal using a Pu code, one of a number of secret codes to identify factories outside Polte, but with the cover story that these codes identified various lines or buildings inside Polte producing the ammunition. Within a few years as more facilities produced ammunition other codes were added which were number codes with a P prefix like P405 for Geco. These P Codes were used into 1939.
Since this box, nor the cartridges use the P Codes, their were clearly not intended for the German Army. The date, 1933 is interesting. it is the year Hitler became Chancellor of Germany and withdrew from the restrictions imposed after WWI but there was a two year wait before the withdrawl could take in effect. This ammunition was likely a way for Hitler and the Nazi party to thumb their nose at the Allies. Since this ammo was not intended for the Army, and is clearly military ammunition, it seems highly probable that it was for some element of the Nazi organization, probably the elite SS which was not receiving equipment or ammunition at that time. In fact, Hitler had difficulty in forcing the German Army to supply arms and ammunition to the SS. There is not a great deal of information on this subject available, at least in English.
If others have information on this subject, please post it or send me a PM or email. There is some evidence that the Nazi units didn’t all begin receiving Army ammunition until sometime in 1943, though the SS combat units engaged in active combat, particularly in Russia, were receiving Army ammunition from much earlier.
Bunker, This is an excellent box and historically important. My deep thanks for posting it.
