Pair of NSB Political Organisation Collar Tabs

Pair of NSB Political Organisation Collar Tabs (kraagspiegels). The Dutch 'Nationaal-Socialistische Beweging' (National Socialist Movement) was founded by 'Anton Mussert' in December 1931 and was a Dutch pro-German Nazi Party. Blue felt collar tabs with three gold coloured bars and silver piping as intended for a 'Kringadministrateur' (local group administrator). The collar tabs are having a buckram backing and are both having an original paper tag attached. The pair is slightly mis-matching, see photos. Nice original pair in good used condition!
