Polizei Strange brown piped SHD tabs

[Paul R]

Here is a very strange SHD NCO level tab.

The typical SHD NCO collar tabs I have seen have the green badge cloth, white embroidered letters, and the broken white/green outer piping.

As you can see, these tabs are a little different. The lettering is embroidered in a deep golden brown thread and the outer piping is in a broken brown and green twist cord.

Now, when I originally bought the tab, I thought that the tab was just a victim of dirt/dust. Upon in hand inspection, this is obviously not the case. It was definitely made in this way.

Was this some short lived regulation protocol or is it to a specific ranking group, which has been forgotten to time(administration, reserve, or etc)?

What are your thoughts?

Clues?

Bringing back to the top for discussion.

Maybe some type of leadership rank? Just a guess. There isn't much out there on the SHD it seems, minus the regulation books which aren't easy to find pictures of

I know.  The images are not great in those books. More like drawings.
