Recently Alan Jackson of Leeds replied to a request for information about the camera obscura at Brightling Observatory that I had left in a guestbook. He wrote:
"I do know that the camera obscura at Brightling Observatory was still there before and during the first part of WWII when my parents lived there. No special knowledge was required for use. It must have been removed sometime later - it was not there when Mother revisited the 'obse' in the seventies."
