Offered here is an original round tin that once held one hundred XXX Triplex Blasting Caps manufactured by the California Cap Company. Full paper label. Includes an insert card showing the cap tin was found in the Luning Shaft (mine) in Mineral County (Nevada), by a well known Nevada Mining Artifact Collector now sadly passed. A tough to find cap tin with the paper label intact, and a dandy display piece of Nevada and California Cap Company mining history. Thanks for looking!
