Flinterman, Jan

[Faster]

Hello to everyone.

I'm doing a research at the career of brazilian Chico Landi, who raced from the 30's until the 70's. At the 1952 Dutch GP, Landi rented a Maserati to the local Jan Flinterman. This gentleman had a problem after seven laps and had to retire, just to take over Landi's car in what was called "shared drive". It was the first time a Dutch driver entered a F1 event. I'll be very glad if someone could help me with the following:

1) Some comments on what he said, details about that race, the rental, the price, why Landi gave his car to Flinterman, anything!

2) If someone knows how can I contact Mr. Flinterman (if he's alive) or someone close to him who could help me providing details, it would be very helpful.

Thank you very much!
