Colourful CD breast badge - war, post-war or repro?

[ARPCDHG]

I would like your valued opinion about this badge I picked up recently.

It is the standard embroidered Civil Defence breast badge but it has been machined/picked out in colours.

I know that the wartime CD armlet was sometimes picked out in colours, but was the breast badge?

Is this a post-war version or even a modern repro? (The jagged edging looks like it has been removed from a uniform and the quality of the machine embroidery says it looks more official than cheap repro, though).

Thanks.
