For anyone's interest, John Clague's amateur 16mm colour newsreel film that had been showing on muted loop at Herne Bay Museum in 2014 as part of the French Dressing at 50 exhibition has now gone to Screen Archive South East in Brighton, providing public access.
It shows Ken and the crew in production at Herne Bay in May - June 1963.
An online preview version complete with Mr Clague's original sound track on reel to reel tape is now viewable at

Aware of many other amateur cine films taken of the production unfolding in Herne Bay that once existed but it may unfortunately be that John's is the only surviving and the only in colour respectively. Thanks to Andrew Clague and Tim Jones at Canterbury Christ University for rescuing this archive and allowing public access for future generations.
