I picked this rather rare medal bar up on eBay recently. I've seen a few other types of these medal bars but this specific anti-gas instructor was new to me. Given that the ARPS also appears it ties in closely with the ARPS Instructor badge that civil defence personnel could train for.
I am indebted to Steve Crookes for sending me this photo of a British Red Cross medal with interesting medal bars from his collection. This shows how the above bar would have been worn. Note the 1941 ARP medal bar.
