The material had been transferred when I started working on it - but as I understand it, they had 2 x Nagra 1/4” machine running pretty much continuously. The cameras were filming sporadically and not all of the audio tapes had been recovered.

My job was a gigantic jigsaw puzzle of watching the pictures and reuniting it with the correct sound for the first time since the original movie.

Nagra made some amazing machines - such incredible precise engineering.
