Instituted by Her Majesty Queen Elizabeth II in March 1961 the Civil Defence Long Service Medal was a long service award in the United Kingdom and associated territories. It was awarded for fifteen years’ continuous service in a variety of different organizations including the Auxiliary Fire Service, National Hospital Service Reserve, United Kingdom Warning and Monitoring Organisation and the Civil Defence Corps. It was extended to Civil Defence personnel in Gibraltar, Hong Kong, Channel Islands, Isle of Man and Malta in 1965.
Description:
Materials: The majority of the British medals and clasps are made of solid silver, though some were issue in bronze versions, mainly to Indian non-combatants. The majority of the British campaign awards are circular, usually 36mm in diameter.
Ribbons: Medals are worn suspended from their own specific ribbons. These were first made of silk but cotton was increasingly used as the nineteenth century developed. Their own colours often have a symbolic significance: the equal stripes of the ‘1939 to 1945 Star,’ for example, are dark blue to represent the service of the Royal and Merchant Navies, red, to represent that of the Armies and light blue to represent that of Air Forces.
Ribbon width can vary slightly though it is generally 32mm wide.
