Flying Wing with Tower, WINCO's Office, Army Major's Office (Intelligence?), Met. Office and mast from where I took the photo of the JV identity sent earlier.   It now surprises me to think that though I occupied this building for nearly two and half years, many of its rooms were never visited; contents in the main were/are a mystery!   John notes in Knoke's book that the Met. Office was the same in his day.   (Thanks to John Hill.)
