The 1982 edition of "The Battle of Britain - Then and Now" (referred to as the "Mk II" edition by the publisher, After the Battle) is the one I bought in 1983. As later editions were published, ATB issued supplementary booklets that included the revised Preface or Postscript portions of the book; I have the supplements to the Mk III and Mk V editions. You could contact ATB to see if they still offer the supplements for the editions which followed Mk II (they still publish the excellent "After the Battle - Then and Now" magazine). TBoBT&N is a valuable complement to any narrative history of the BoB, IMO.
