History

The DAF (Deutsche Arbeitsfront = German Labour Front) was the result of a forced association of all German trade unions, established on May 10, 1933. Its purpose was the coordination and control of all aspects of German labour to serve the interests of the NSDAP. The DAF leader was Reichsleiter Robert Ley.

The Werkscharen (Factory Brigades) of the DAF were the “soldiers” of the organisation, formed in 1934. They were trained and organised as paramilitary, uniformed units, yet remained unarmed. Beginning in April 1937, active Werkschar units (Stoßtrupps) would wear silver-coloured insignia, while administrators wore gold-coloured insignia. Even though Werkscharen were not affiliated with the Reichsluftschutzbund (RLB, National Air Raid Protection League), during the war they often functioned as factory air raid protection auxiliaries.
Some companies, especially major corporations, used additional security personnel, which were dubbed Werkschutz (Factory Protection), and later Werksicherheitsdienst (Factory Security Service).

The NSBO Cap Insignia features a right hand holding a hammer with a static swastika, attached to a cogwheel section with the letters “NSBO” on it. Caps featuring this insignia were only worn by lower leaders and regular enlisted ranks. The insignia was made of white metal for regular members and silvered metal for lower leaders. It was discontinued in December of 1935.
