According to the IWM no list has been found.
The badges do have a unique number on the back and there would have been a register that recorded the issue of these badges although it has not been found. So, there is little more that can be discovered about individuals from these badges alone. However, they can of course give clues as to a person’s role in the war effort, if it is known who it belonged to.
