A 1933 Landestreffen der Nationalsozialistischen Betriebszellenorganisation (NSBO) in the district Nessen-Nassau (Frankfurt - 27.8.1933); In die stamped bronze, horizontal pin on reverse; unmarked; measuring 45 mm x 28 mm; better than very fine condition. Footnote: The NSBO was a workers organization of the NSDAP. It was established in 1931 but gained little support until it began to used aggressive propaganda campaigns with the slogan “Hinein in die Betriebe!” (Into the Factories!) to increase its member base. However, compared to other Democratic and Christian labour units, the NSBO was only mildly successful, having only 300,000 members.
