The Fast Lady

Hi, the pictures fl001 and fl002 were a set filmed at Beaconsfield Studios and the building at the back, is the front of the studios. I'm interested in the Fast Lady as I own the black Rolls Royce "200 DYO" which "JRJ" drives and knocks Stanley Baxter off his bike. Could you please help me as I would like to know where the large white house is in the film. I have more pics if you want, of this film ,with my R-R.
