An interesting letter appeared on eBay concerning Post Warden stripes. Sent to a Fire Station in Pinner, the letter (dated June 1943) outlines the badges received are the printed variety and not the material (I assume embroidered) type (that were hoped for it appears). The letter from H.U.D.C (Harrow Unitary District Council) details that existing badges will need to be returned when these are issued. Clearly the person receiving the badges wasn't overly enamoured with the printed badges and simply filed the letter. Slightly curious is the whilst the letter is dated 2 June 1943, the letter's date stamp is 25 May 1943.
