The Narrow Margin, Wood & Dempster

[Dick Powers]

Although I don;'t have NM at hand presently, it was a ground-breaking study. It covers development of radar, the air forces and presents the BoB in a diary format, describing the BoB action for each day. Losses are given in numbers only with no attempt to identify each loss. These is an appendix By William Green, I believe, which briefly describes the history of each major aircraft type, along with a Dennis Punnet drawing.

I still have my weathered first (American) edition. It compares with Mason's "Battle Over Britain" a;though Mason's starts with Geman raids in WWI and gives loss details.

I have seen NM at used bookstores reasonably priced.It's definately worth having, although I doubt that it will give you new information or a different point of view.

Some of your questions about "how narrow" are discussed in Richard Overy's book "The Battle of Britain: The Myth and the Reality" which, although small is definately worthhaving.
