Is anyone able to identify this uniform please? It's a photo of my Great Uncle, born in 1902, so it rules out WW1 unless he joined up towards the end of the war. It mentions on the 1939 census that he was a volunteer dispatch rider for the ARP but I can't find this type of uniform when I do an internet search. I can't find any military records for him so I've hit a bit of a brick wall. I can see horse badges on his uniform so could he have done something with horses?
