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 NSBO (Nationalsozialistische Betriebszellenorganisation = National Socialist Factory Cell Organisation) was a labour union organisation founded by NSDAP members in 1928. It started out local and mainly Berlin-based, but eventually grew into a nationwide organisation by 1931. However, the DAF was seen as better capable to carry out the will of the NSDAP leadership. This resulted in the decline of the NSBO after the DAF’s establishment in 1933 and concluded in the eventual absorption of the NSBO into the DAF by 1935.

The NSBO membership pin is in the form of the organisation's emblem, a right hand holding a hammer with a static swastika, superimposed over a section of cogwheel with "NSBO" on it. The membership pin measured 15x15mm and featured a needle pin on the back. It was worn on the lapel of civilian dress or on the tie when in wear with the uniform.
