Offered in this lot is this Rare S. L. Hart Wood Handled Leatherwork Knife, circa 1880 to 1890. Provenance: Tombstone Western Heritage Museum, Tombstone, Arizona. Knife has Hart's famous stamped logo, which was the letters S and L over a "heart", an artistic yet compact and simple way of saying "S.L. Hart." Samuel Lombard Hart (1830-1893) was a very highly regarded and skilled gunsmith over his ten years in Tombstone. If gun repairs were needed, Hart's on Freemont Street was the place to go, located just a short distance from the famous Fly Photography studio and right next door to the O.K. Corral. On Oct. 26th of 1881 Hart, while working in his store, would be one of the relatively few witnesses to the Gunfight at the O.K. Corral that made Tombstone and the Earp's famous. Guns that were re-worked or repaired by Hart were often stamped with his logo, which was the letters S and L over a "heart," an artistic yet compact and simple way of saying "S.L. Hart." S.L. was entrusted with both basic repairs as well as also sought out for his special Colt pistols. Some of Hart's more notable clients were US Marshal Wyatt Earp, Doc Holiday, outlaw Ike Clanton and Buckskin Frank Leslie. It has been said that the legacy of S.L. Hart as gunsmith to the cowboys, gamblers, lawmen, and gunfighters of Tombstone cannot be over estimated. A "Tombstone" Colt Single Action Army Revolver with Hart's markings on it sold at a Rock Island Auction Company 2010 auction for $32,500.00. Today a firearm with the "S.L. Hart" stamp is almost priceless. Letter included is from Marjorie Elliott, Curator and President of the Tombstone Western Heritage Museum that traces ownership of the knife from the Hart Estate through S. L. Hart's son Kirt, who was a gunsmith in Tucson, Arizona, to a lady who had a large collection of Hart items, from whom the Tombstone Western Heritage Museum received them. The knife has a leaf shape blade point, triple brass riveted wood handle, encapsulated tang. Rich patina observed on both blade and handle. Tombstone Western Heritage Museum code, "G233." Total measurement 7"L, blade is 3.25"L. Weight is 62gms.
