(I'm French, therefore, thanks in advance to forgive my approximate english !!)
As for the pictures and for the remarquably well documented text, "the Winning Formula" is definitely excellent to present the entire story of 917 Porsches and their context.
Having said that, the book might not be suitable for the ultimate specialist seeking any possible detail upon this fabulous "warbird", but it's one of the best generalist one, precise enough and full of anecdotes to fulfil any amateur's expectations.
... All this at a very reasonable price, considering the quality of writing and the number of superb pictures.
Thanks Haynes. Waiting for a lot more about Lolas, Matras, Ferrari 512s, ...
