UBB.threads Forums General Militaria Historic and Period Firearms Forum Help with Holster marks

Vern, I kind of agree with you that the circular stamp indicates the Bosch firm, but I think the stamp is a general property stamp of the Bosch Factory Air Raid Service. I have no concrete evidence but I believe the darker stamping SGMG/WSZ indicates the particular subsidiary factory where this gun/holster was used. I base this belief on some info found in the Wiki article on the Bosch concern. As a result of the Nazi economic expansion in preparation for war, the Bosch concern was "convinced" by authorities to relocate factories to the interior of Germany. One of these factories was identied as "Bosch subsidiary Dreilinden Maschinenbau GmbH (DLMG) in Kleinmachnow near Berlin". Notice the abbreviation used for the factory name. So, I think it logical that SGMG was the abbreviation for another of their factories located in the city/town abbreviated WSZ. As I wrote, I have no concrete evidence, but it certainly seems logical.
