Sailor-turned documentary maker Des Cox owns one of the world's biggest maritime archives: a celebration of the golden years of British shipping.
When he was handed reels of film from the 1920s - film that was about to be thrown away - he expected it to come to nothing. Not least because the film was in an extremely fragile state.
