Offered here is a very rare original 1890's Box End that was once attached to a box of Number 2 Powder manufactured by The Judson Dynamite & Powder Company, San Francisco, California. Measures 12.25 x 6.25, likely off of a 50 pound size box. The Judson Powder Company was organized in 1890 and acquired by the DuPont Powder Company in 1903. The Judson name was discontinued by 1912. Tough to find these early powder company box ends out of collections. This one from the collection of a well known Reno Nevada Mining Artifact Collector and Geologist, now sadly passed. Great display piece of California Mining History with a wire on the back attached for hanging on a wall. Thanks for looking!
