I believe this is a World War Two AIR RAID POLICE BADGE ?, it is Nickel Plated, King’s Crown A.R.P. and numbered on the back 11933, so it would have been an issue badge to an individual, approx. size 36mm by 45mm. Have looked countless times on the internet and have found a few photo’s of this badge but no explanation as to what it is exactly, the 3 photo’s that I found describe it as Air Raid Patrol, Air Raid Precaution and Air Raid Warden with no further explanation. Is it a br...east badge or a wallet badge? SHIPPING AND HANDLING $3.00CD IN CANADA AND $4.00CD TO THE UNITED STATES AND $7.00CD TO INTERNATIONAL DESTINATIONS
