Richard Seaman Trophy Races 1951

[F1History]

Hello Members,

I´m new at this website and a german historian in F1.

I build a database about all F1-Drivers who has collect minimum a single,
(or half) point at World-Championship-Races since 1950.

These are about 299 (one female) and 34 drivers from the races Indy 500 1950 - `60.

I also look for all race wins in other categories, Sportscars, TouringCars and all formula racers. (F500, F3, F2, F3000, Tasman, F5000... and the american series.)

Since today I "worked" at the british Driver Dennis Poore and in the book 4th edition Grand Prix Who´s Who I read that Poore became 1951 to 1953 Winner of the Dick (Richard) Seaman Trophy Races.
I´m searching half of the day to find which races was counting therefore
but I found nothing.
Not in my 300 Books, and not in the www.

Can anyone give me assistance??

Thank You
