'National Sozialistische Betriebszellen-Organisation' (NSBO) Cap Badge (Mützenabzeichen). The NSBO was a workers organization in Germany, established in 1928. In 1935 the NSBO was merged into the DAF, a more organized and better represented organisation. The cap badge is sized approximately 2,5 x 3 cms. The cap badge is complete with a functional pin-back system. Nice example in good condition!
