You're welcome! I haven't found it on GE yet, but according to the site, series 8-10 were filmed "hidden deep inside a military base near Bramley in Hampshire".
Haven't found any other of the older sets, but I doubt there are any remains left.
Try GE at location 51 degree 19' 08.02" N 1 degree 03' 44.13" W best viewed at elevation 60 metres and I am sure it is buried in the forest somewhere, but I am also pretty sure the GE's map data is before the filmset being there..... or is it there ? let us know folks.
You'll find that most of the google satellite pictures are at least 4 to 5 years out of date, the set is on there BUT it is prior to RDF taking it on. It was obviously still MOD property then because now it is much scruffier and untidier !
have a peep at the Steve G site cuz it has both the before and after views of the filmset. looking forward to this sunday sounds like it should be a good un
