Thank you, I don't have these drawings Currently, I'm working on some new ways to model them. I want to do a perfect model with the most up-to-date technique, I will be really demanding with myself. I continue making list about rims and so so I find more and more pictures of Van Rooyen's car I will take a look about other cars too very very slowly after making list about M7... 2 cars which are driven by Surtees (as Mclaren M7)
https://www.forocoches.com/foro/showthread.php?t=1519331 A good collection of original photographs...
The research continues I edit my first post with the variation of M7 race by race, it will be continue from 1969 to 1971 and I'm not full happy about 1968 I will do a pdf with different photos when I finished to list the variation...
I don't know if it could be helpful, but I have some engine numbers from the book "Dall'aerodinamica alla potenza in Formula 1" by Enrico Benzing. It's in italian, but it's all easily translatable. If you need help, feel free to ask me. So the M7A raced with the Cosworth (here the 1968 and 1969 spec) and the Alfa Romeo engine (on the right).
Thank you I save it! Are there some sketches in this book? Any values about anything are interesting! (about Mclaren M7,Ferrari 158-1512-246)
I'm currently doing a F1 Tires database already sent to Mauricio Leiva, I will maybe extend to 79 https://www.dropbox.com/s/w80fnc4p4wcq35g/TyreF1.xlsx?dl=0 it comes from one source until now ( http://www.silhouet.com/motorsport/ ) This weekend I will come back on my final list about M7.
