Re Remington-duPont. At that time, Remington was a division of duPont (E. I. duPont de Nemours), the large chemical company. duPont bought Remington back during the Great Depression of the 1930s. If you look at Remington products from back then (and later), they will always have the duPont symbol on the packaging and any printed materials (duPont inside a lozenge).
