There are quite a number of books that cover British aeroplanes/light aeroplanes that include types that took part in the Lympne trials in the early 1920s – as well as several of the Putnam series on British aircraft manufacturers. Lots of photos of aircraft taken at Lympne (during the trials) in these.

I wonder has anyone written a book specifically about the Lympne Trials (1922 to 26?)
