Volkssturm Gau 3 - Berlin

[WARNACH]

Good evening

For some years now, and after my recent retirement from active duty even more intesively, I'm doing research on the Berlin Volkssturm.
I collect all possible "paperwork" like Soldbücher, documents, newspapers etc ... and also all available digital archival material on this subject.

What I've never found/seen was a genuine Berlin Volkssturm Erkennungsmarke.
Is there a collector on this forum that owns such an EKM?
3/.../. - .. DV (possibly with "z.b.V.")

Thanks
Peter
