This is an arrmband from the dutch Interior Forces (Binnenlandse Strijdkrachten) from the period of the liberation in May 1945 in the Netherlands.
This is the very rare First Model “CD” Civil Defense armband. For identification of NBS members were at first used english CD armbands. before the more wellknown black armbands with white CD letters were in use, there was a short period in which older dark blue armband were used. The here offered armband i one of those!
To make it even better there is also a CD arm patch included. Found together like this. Only the firt we could ever offer.
Very hard to find Dutch liberation/resistence items!
