The Sources
Well, although all information provided here is coming from my private collection of books, magazines, pictures and else, I already can hear the sharks of the so-called "CopyRight Law". My answer to them is: "Leave me alone, this site is for education purposes only, nothing commercial...". But because I respect the work of the writers and editors, here is the sources of information I have referred from:
Moto d'époque et d'exception
French magazine, very well done.
Alpha Auto
Editions Erasme
