NSB Membership Badge (NSB Draagteken). The Dutch "Nationaal-Socialistische Beweging" (National Socialist Movement) was founded by 'Anton Mussert' in December 1931 and was a Dutch pro-German Nazi Party. These membership badges were worn by all party members. The enamelled badge comes on its original buttonhole attachment. There is some enamel damage. The badge is not visible maker marked. The badge comes on its original and functional buttonhole attachment. Nice original NSB Member Pin!
