RAF sweetheart brooch

Jimmy, my dear friend gave me this most precious RAF sweetheart brooch.  Pilots during the 2nd World War gave their loved ones this brooch before flying off to fight for their country.  Jimmy gave this to his darling wife, Rita.  When Rita passed away, he said I could choose any piece of her jewellery and this is the special gift I chose.  The ribbon behind the brooch was given to Jimmy when he was released from the RAF, supposedly to proudly hang his medals from (which he never collected!)
