The RAF unit at Gillingham was officially called Royal Air Force Element, Maritime Headquarters, Chatham. and for postal address it waS RAF Element,
c/o Admiralty House,
We didn't have postcodes in 1957 when I was Corporal in charge of the RAF Orderly Room for 16 months. I enjoyed the posting there but it's sad to see the state of our area and the underground Ops Room etc now.
