Elmer Merrifield Keith, born March 8, 1899, was many things; a rancher, cowboy, big game hunter, shooting sports legend, and innovator in the world of magnum cartridges. He is responsible for the development of the iconic .357 Magnum, .44 Magnum, and .41 Magnum cartridges. The included letter of provenance states the revolver was purchased from the estate of Elmer Keith in March of 2015 and confirms the model, serial number, and caliber. The included factory letter states the revolver was shipped from Ruger in June of 1971. Finally a laminated copy of a page from Elmer Keith's personal collection book lists the revolver by serial number and caliber. Fixed blade front and adjustable rear notch sights, standard markings, scarce brass grip frame, and custom tuned trigger. The grips are smooth with an inset silver elk head on the left panel and silver inscription oval on the right inscribed "Elmer Keith" in fancy script.
