When I joined in '63, one of my fellow Brats had a King's Crown cap badge, given him by his grandfather. It was slightly more oval in shape than the Queen's Crown version that we had as standard issue and bore a King's Crown, but "Cookie" wore it every day and on every parade. Those who were Brats will know how often that badge was peered at (and even on occasions removed to see if there was any Brasso residue on the back...) on parades, but he was never picked up for it.
Even though the letters in the middle were RFC instead of RAF...
