It was all started to identify the plants that made the „secret“codes for Spain.
Some companies did not know what the meaning of this “Tarnkode” was.
Perhaps it became that in the beginning cases from the normal production were used for export to Spain. They were not made at German specs, like primer crimp and annulus colour.
The picture shows an example from P131 and P413 head stamps, how to recognise these rounds.
The first example is a box from DWM Lübeck P413 with the Code AI on the label.
We found out that the character “A” was given to the DWM concern and the “I” was given to the plant Lübeck.
The Polte concern became the character “B” In 1938 the left over’s were used in the SmK 4th lot of 1938. Polte Magdeburg BI
By making the export order there were always some left over’s. They did not throw them away, but used them in the normal production like the P186 (Metallwerk Wolfenbuttel “Polte”) made with BII cases or the P315 who get D3 cases to make blanks of them.
Sometimes we were lucky because it did not matter witch head stamp a practice cartridge had.
Here an example from a Polte box with a 7,92 head stamp, packed in a box of lS rounds with left over cases from 1937. and a B IV in a box from P154.

After the export order to Sweden was cancelled, the cases were used for ammunition for the “Wehrmacht” . Only the cn plated bullet was changed to a Tombak bullet, so it is easy to identify this cartridge.
There were also a few so called “Munitionsanstalten”. These were facilities were ammunition was checked on damage and functionality. They repacked the ammunition in boxes were the facility was printed open on the label.
Perhaps they thought that these boxes never leave German territory.
