The last question: the 375MM in the back of the photo (nº9) is from Masten Gregory (#0370AM)? or from Piero Scotti? Thanks
Now you are talking of that, I have checked the pics I have and it's true that number 9 is clearly s/n 0366AM (chrome around grill after a crash and headrest) and so, number 9 was de Oliveira and not Gregory...
Fantastic, the brother (Casimiro de Oliveira) of the older film director of the world, Manuel de Oliveira, that i know personaly. It´s in good wealth... Manoel de Oliveira was also a racing driver.
