Richard Seaman Trophy Races?

[F1History]

I´m building up a Data-Base with all F1-Point scorers since 1950.

I look also for Race wins in other categories (Nonchampionship Races F1, F2, Tasman Series, CanAm, (World-)Sportcars and Touring cars of these 299 people.

I use therefor the also the Book Grand Prix Who´s Who, 4th Edition and when I wrote about Dennis Poore I read there that he won the Dick Seaman Trophy Race in a row 1951 to-53.

I was searching in my books and the www. but didn´t find where and which races was count to the trophy??

Can anybody help me with datas and results of the races?
Where and ´when the race??

With Regards
Karl-Heinz
