I knew it would be fast...
India 42 and Nvubu have it spot on (however the locations which seem to come from LdZ compilations are rather wrong)! Caffiers and Guines are well visible; Fiennes airfield is on the side of the forest NE of Fiennes village on a rather narrow ridge overhead Fiennes (this is coherent witha Bf109 photo I have seen wehre the A/C was parked on the edge of the ridge).
OH to one of you!
