I recently blogged about a Dutch 'CD' armband issued close to the war's end. Jon Mills has sent me the following information regarding a similar armband but with light blue lettering made by the GPO. The lettering on the Dutch example looks white when compared to the below example, but it could be faded. The design of the GPO armband looks identical to the Dutch example. This armband is noted as "ARP Pattern 194 Armband, Industrial Civil Defence - Light blue printed on dark blue". See this page for a list of ARP Pattern Numbers.
The previous source mentioned that the Dutch armbands were issued by British forces and it would now follow that these were indeed British in origin.
