This collar tab "came with" the collection I bought recently. By "came with" I mean that he literally threw it in as he could not authenticate it. I saw that at least two ranks had the SS runes with no piping around the edge (Sturmtscharführer or Hauptscharführer as listed above) and the runes themselves have a decent symmetry and position on the tab.

The stitching is slightly odd though, in that the center is not as dense or "filled in" as other examples I’ve seen. The edge of the runes seem to have a pronounced border as well.

Halfway decent fake, or real after all?

As always , thanks to all!
