William Sanderson: World War One Munitions Factory Worker

I previously wrote about my grandfather, William Sanderson, (William Sanderson: The Early Years), having worked in a munitions factory, likely somewhere in Cambridgeshire, during World War One. He always said it was his first job at the age of fourteen in 1917. I came across the following video of munitions workers in Britain recently, and wanted to share it with you as it helps to show what this work may have been like for him.
