Guaranteed original; c. 1970s. This is an original 51 Squadron RAF Royal Air Force PLAQUE Badge for sale. These plaque badges measure about 40mm X 25mm and have each been hand enamelled with embellishments in 24 carat gold. They were issued by the Danbury Mint as collectable souvenirs for veterans and collectors alike back in the 1970s and are now very hard to come by. These are the larger plaques as opposed to the lapel badges and so were issued WITHOUT REAR FIXINGS. A very nice RAF Squadron souvenir.
