LugerForum Discussion Forums - Unit Marked Holster

I picked up this holster and have been researching it. Based on information gathered on this website, its Crown/III mark indicates it was issued to the Bavarian 3 Armeekorps and was made no earlier than 1918. I can not make out the maker mark in the inside flap. Possibly made in Nuremberg, Fürth , or Munich. I think it was used during the Weimar era and later during WWII based on its unit mark.

I believe Nachrichten-Abteilung 7 may translate to: Communications Section or Intelligence Division 7. Possibly this was a communications department stationed in Bavaria during the Weimar Republic, and/or later issued to the Nachrichten-Abteilung 7 of the 7th infantry division during WWII. Let me know if I am on the right track on determining the unit mark and history.
