Reichswehr Ministry marked Luger holster

[Skookum]

Hi,

I have had this holster for some time. I collect unit marked Lugers and holsters, focusing on Reichswehr unit marked variations.

I have been trying to research the holster marking, to determine which Nachrichten unit, or detachment, this would be. And / or it's history.

Any thoughts or knowledge would be appreciated. The 3rd Division Nachrichten Abteilung was billeted at Potsdam, so I'm leaning toward it.

Thanks...

Ron
