Brabham BT18 wnner Crystal Palace

[JayandShel]

Hi All
I'am currently researching the cars that took part in the last race meeting at Crystal Palace on the 23 September 1972 it was an eight card race meeting and have come to a bit of a dead end regarding race 2 and 4. Race 4 was a Monoposto race which was won by a Brabham BT18 (MGM?) driven by a Trevor Scarratt I was hoping someone on here may know more about the car in question or perhaps have links to Mr Scarratt next year will be 50 years since the circuit was closed and was hoping to possibly put together something that can mark the event,
any help would be greatly received
