Evening All,
Like pierrelm I too have a much loved (and thumbed) copy of the Hippo book, and its WW2 partner. I cannot remember how old I was when I bought it - probably in my early teens - but one photo always stuck in my mind because it was of a type that I badly wanted to have as a model but could not. It was the Maurice Farman 7 Longhorn:

Approximately 50 years later I decided that the photo needed to be brought to life, so I scratch built my own MF 7! (there is a build log on this site).
Another volume that I bought a little later was this:

Note the price - 4/6d - approximately 23 pence in modern Sterling, but at the time a considerable sum, especially when all I had was 3/- a week pocket money! Still a treasure trove though.
At Christmas 1966 my brother gave me this:

which really aroused my interest in the aviation of this period. What Funderburk left out though was the intense cold, oil all over the goggles and face from a rotary engine, unreliable engines and jammed guns, and all the other non-glamorous aspects of early flying. Still a very good read though, especially for a boy in his mid-teens.
Stephen.
