This RAF No 1 Fighter Squadron badge is a single example and was originally from a collection of twenty five RAF Squadron Crests depicting the fighter Squadrons that participated in the Battle of Britian and was issued by the Royal Air Force Museum as a numbered limited edition to commemorate the historic Battle over England’s skies in 1940. Each crest was inset into the red velvet and housed in a glazed gilt frame with brass plate to centre bearing a facsimile signature of Group Captain Douglas Bader.
