The bottom line: he was never entered for Monaco, but did co-drive his car in Argentina with Jean Behra.
He typed the letter on a typewriter, but as he is quite frail, I wouldn't like to post it as it is, I rather typed it.
With the fall of the Peron government in Argentina, the main market for Maserati, where they sold milling machines, Argentina refused to pay their debts. Maserati’s main production was milling machines, they had to stop racing, close to bankruptcy and now controlled by the banks.
The official machines for 1957 were 2527, 2528 and 2529. The last car built in 1956 was 2526. In practice it was used as a hack car to get the gear ratios correct on the others in 1957. If not broken it was driven by Giorgio Scarlatti.
At the end of 1957 Maserati asked ex-motorcyclists if they would race for them but had to pay the expenses. I accepted and was given 2527. I tested the machine at Modena around Xmas 1957. Both Maserati and myself were happy with the results. The ship had already left Genoa with all the machines for Argentina, the first G.P. The car had to be sent to catch the ship at a French port.
All the drivers left about a month later on a special plane hired from Brazilian airlines. It was on this flight that I met and became friendly with the G.P. drivers.
The G.P. was run under terrible conditions, perhaps around 50 degree heat and impossible humidity. I shared my car with Jean Behra, but this is never mentioned. Stirling Moss drove a Cooper-Climax. This was a simple [unreadable] and the Climax was a common water pump engine of 1.5 liters on sale in England. The Moss car was built and entered by Rob Walker of London, but the Climax was bored out a little of over 2 liters.
With the front engined cars such as Maserati and Ferrari the heat was terrible. With the rear engined it was much cooler and the race was won by Moss. This signalled the coming end of the front engined cars.
I was to race in 6 more races but the Maserati was terribly expensive to maintain, whereas the Cooper was very cheap. The organizers wanted Coopers, drivers would accept less starting money.
In the Monaco G.P. the ex-works Maseratis were driven by Scarlatti, this was the car driven by Fangio in Argentina, the other by Maria de Filippis. I wrote for an entry but they wrote back and said NO. So I was never entered.
My next race was the Belgian G.P., but on the last practice lap the engine broke a con rod, and there was no time or spares to fix the engine for the race. The same thing happened to Masten Gregory. His was a Centro Sud Maserati. But they kept quiet, started on five cylinders just to get the starting money, and retired after half a lap.
I told the organizers what had happened to my car and for being honest they gave me half the agreed starting money to help cover expenses. After that Goodwood meeting [1959/03/30 Glover Trophy] I was entered to race at Aintree, but the son of a friend of mine, Harry Hinton, was seriously injured at Imola, falling from his Norton and the doctors asked me to stay in the hospital as no one spoke English. Hinton Jr. died after two weeks… after all this trouble I decided to return to motorcycling.
I finished doing public relations for Ducati, returning to Australia Xmas 1959 after 10 years to search for an importer, arriving there as a guest of the Italian embassy. I retired after Monza 1960.
And this is all true
So that also means that he should have scored a World Championship point for his Argentine fifth place doesn't it?
