NSB 'Werkersbijeenkomst-22/10.38-R.A.I.-A'DAM' Tinnie. The Dutch "Nationaal-Socialistische Beweging" (National Socialist Movement) was founded by 'Anton Mussert' in December 1931 and was a Dutch pro-German Nazi Party. With the 'Hagespraken', the NSB wanted to emphasize the unity of the party. This event was held at 22 October 1938 in the 'R.A.I.' in Amsterdam. The badge comes on its functional pin and is not maker-marked. Very nice looking example with great finish, hard to find in this condition!
