It's always interesting to see the uniform regulations being bent. This pretty standard group portrait of (probably) wardens features a lady on the bottom left wearing a male battledress. It's rare but not unheard of to see period photos of females having managed to get hold of a battledress. Apart from that it's a pretty standard photo of uniforms and insignia. Appears that the majority of berets have the printed CD in a yellow circle. That's a bit unusual as those with ARP badges usually fixed them to their berets. There's a member of the Home Guard lurking in the photo as well...
News about interesting insignia, ARP related info and period photos that turn up.
