Got these in today, a DWM and a Mauser document. The DWM one is dated around 1913, the Mauser one dates from WW1, 1917.
They are both declarations that testament to the worker's history at the company and why/how they were discharged.
Haven't deciphered everything yet, but the Mauser worker Polla had worked at the Feuerback branch of Mauser until the 4th of april 1917. Reason for his discharge is that he joined the army.
