Busy at work on the background of a London office, our trainees who are learning to operate the race finished recording camera, better known as the photo finish camera. When they are fully trained, these operators will form a mobile squad, visiting tracks where the camera will be installed. Close finish races will no longer rely solely upon the judge's decision as the finish of the race, name of the racecourse, race and date will all be photographically recorded. Picture shows: instructor KJ Dunkinson points out the "spin" (this records the name of the racecourse, race and date on the negative) to trainee R.Bettel, on a model racecourse used for training purposes. 24 March 1947
