Item Description
This extraordinary First Generation Colt Single Action Army U.S. Artillery Model represents a captivating blend of American military heritage and Old Hollywood legend. Originally inspected by Henry Nettleton, whose “HN” ordnance stamp appears on the frame, this revolver was part of the historic U.S. Government arsenal during the late 19th century—a period when Colt’s SAA served as the backbone of American cavalry and frontier defense. Later arsenal rework conversions into Artillery Models are among the most desirable 19th-century Colts, as they often saw extended service through the Indian Wars and Spanish–American War, linking them directly to the nation’s military past. Adding even greater intrigue and collector appeal, this example bears the “S” marking above the serial number, identifying it as a firearm once supplied by Stembridge, a renowned Western movie company supplier that furnished authentic Colts for classic Hollywood productions. Combined with the “.45” frame marking, this revolver bridges two worlds—the battlefield and the silver screen—embodying both the rugged reality of U.S. military service and the enduring romance of the American West as portrayed in film. Very few pieces unite such tangible connections to U.S. cavalry history and cinematic heritage, making this a once-in-a-lifetime opportunity to own a true Colt that lived both history and legend.

Bryant Ridge's Analysis:
The Colt Single Action Army, famously known as the “Peacemaker,” is one of the most celebrated revolvers in American firearms history, embodying the ruggedness and independence of the American frontier. First introduced in 1873 by Colt’s Patent Firearms Manufacturing Company, the Single Action Army was originally chambered in .45 Colt and designed as a reliable sidearm for the U.S. Army. Built on a solid steel frame with a six-shot cylinder, the revolver utilizes a single-action mechanism, requiring the hammer to be manually cocked before each shot. Early models featured a simple fixed front sight with a rear notch, ensuring durability and ease of use in field conditions. Over time, Colt produced the revolver in multiple barrel lengths, from compact 4.75-inch models to 7.5-inch “Artillery” versions, as well as in a range of calibers, allowing it to adapt to military, law enforcement, and civilian needs. Its combination of mechanical reliability, robust construction, and accurate performance quickly earned it a legendary status among soldiers, lawmen, and frontier settlers alike. The Colt Single Action Army has evolved through several distinct generations, each reflecting changes in design, manufacturing methods, and market demand. The First Generation (1873–1941) consisted of the original military and civilian models, noted for their hand-fitted parts, crisp action, and classic finishes. The Second Generation (1956–1974), produced after Colt’s factory reorganization, introduced modern materials and slight dimensional refinements while retaining the traditional appearance and single-action mechanics. The Third Generation (1976–present) saw a broader expansion into commemorative and custom models, including factory-engraved editions, varying calibers, and specialized finishes, appealing to collectors and enthusiasts. Each generation maintained the revolver’s iconic silhouette and single-action operation while improving consistency, durability, and aesthetic options. Today, the Colt Single Action Army remains not only a historically significant firearm but also a symbol of American heritage, with examples from every generation valued for their mechanical excellence, cultural importance, and collectible appeal.
