A makeshift clock was erected outside the workshops of Springfield Armory shortly after the United States declared war on Germany on April 6, 1917. Instead of time, the clock measured rifle production in the thousands. It served to remind and motivate workers to speed production, do your bit, and always push the green hand ahead! The story of Springfield Armory in the First World War is one of pragmatic decision-making and creative problem-solving. The sudden involvement in a massive industrial war forced the exploration of non-traditional labor pools and a new reliance on private industry in order to arm and equip a rapidly expanding American Expeditionary Force.
