“Footage of Chilwell shell factory found in shed seen for the first time in 100 years
Originally filmed by the War Office in 1917 to show the daily lives of munitions workers drafted in to help with the war effort, the Kodak film was in a terrible state when it was found in a garden shed four years ago. Following painstaking work by film technicians at IWM, the film can now be seen a century later and is available for licensing.”
