NSB - WA (Weerafdelingen) Machine Woven Shirt Arm Badge intended for wear by the 'NSB'-related: 'Weerafdelingen' (being more or less the equivalent of the German SA or 'Sturmabteilungen'). The Dutch "Nationaal-Socialistische Beweging" (National Socialist Movement) was founded by 'Anton Mussert' in December 1931 and was a Dutch pro-German Nazi Party. The Dutch-made arm badge is nicely machine-woven. These badges were in my opinion specifically intended for wear on the black linnen shirts. Desirable and decorative WA Arm Badge in good used and clearly shirt-removed condition!
