I just happened on a copy of the July 1958 Motor Sport at a classic car show, maybe the best 50p I ever spent.
It has coverage of the British and \French GP's plus DSJ's very long article on the Monza 500 mile race between the USAC and European cars. DSJ wrote an unusually long race report and a big feature on the cars.
It is pretty clear he got really excited about the high speed track racing and the wiliingness of the Indy drivers to race wheel to wheel at 180 mph. He covers the sheer bravery of Musso in a evil handling Ferrari and goes into more detail on Moss's mental state before and during race then I recall him writing elsewhere.
DSJ's enthusiasm for this event has whetted my appetite for more on it. Are there any videos out there showing the racing please apart from this one?
