I'm still going through a bunch of tags in the reference books. These came out of “The German Infantry” Ulrich Herr, Jens Nguyen, Verlag Militaria , Austria , 2008 (English )
The first one provides a fly in the ointment, as it appears to be a sample from a specific supplier and is called Probe not Muster.
Some general observations as I am thinking aloud. There seem to be different kinds of tags.
Tags originating at the War Minister.
Tags coming from specific suppliers.
Tags associated with specific army corps.
A group of tags called Nachprobe which seem to be product improvements, but I cannot tell if they are from the supplier or the Bekleidungsamt.
There seem to be a general feeling that these are "acceptance" samples. I am not sure what that means.
An idea of the flow would be that the specifications are written by the War Minister. Those specifications are then sent to the various army corps. The specifications are then put up for bid, and those firms winning the bids send a sample (Probe or Muster) back to the Army Corp. for acceptance. If accepted by the Army Corps, the sample is sent up to the War Ministry, and sealed. It seems as though the red seal comes from the War Ministry .The War Ministry takes a sample from an army corps, like the Guard Corps and accepts it as the kingdom wide standard, giving it a seal. If this was the flow there would be no need for any upstream subcontracting to create the "original" sample. However this would allow different Army Corps to nominate samples from different suppliers. The Nachprobe would follow the same path, starting at the supplier and being sent up initially to the Army Corps and then to the War Ministry for acceptance I am still looking at tags….. any other ideas are appreciated.
