Hi Mervyn,
Many thanks for your reply. I have in the past collected Police items from the 1940s, i do have a Black and White Duty arm Brassard with the metal buckle circa 1938, i also have a Blue and white one with press stud fastening (reproduction me thinks). The Green and White one is a mystery to me, it is made from the same material as the Black and White one and the same size however it fastens through a material loop, it was suggested that it maybe Ministry of Defence issue am not sure?? did ambulance drivers have a similar system for when on duty??? i dont know:blush: forgive the smillies.
regards Keith.
