NSB 'Zwarthemden Bijeenkomst' 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. This event was held in the Mobilisation year 1939.  The tinnie is showing the text: 'Ik roep hen die zijn 't vaderlant ghetrouwe tot in den doet' (I call to those who are faithful to their fatherland). The zinc type tinnie comes on its functional pin/catch system, the tinnie is not visible maker marked. Nice example in good used condition!
