Information and discussion on all aspects of British photographic history
There is a website devoted to the film (http://www.gandolfi-film.co.uk/) with a contact phone number: Michael Dixon / tel: 07974 679199.
In mid-2012 Michael Dixon told me that the process of generating a DVD had begun, so I hope there may have been some progress. I haven't heard anything, so if anyone has any more news I'd love to hear it!
There was a much earlier (probably late 1970s) programme shown on, I think, BBC television. It showed Fred Gandolfi in his workshop, talking about the cameras and how they were made. I believe that I still have a copy of this that I made on VHS tape, which might still be playable. I'll look into it.
If you do manage to track a copy of the film down The RPS would be pleased to host a public showing at our headquarters in Bath. I remember Fred Gandolfi giving a talk to the RPS Historical Group in the early 1980s in London.
