Detailed Firearm Description Firearm: Browning Auto-5 Light Twelve Semi-Automatic Shotgun Manufacturer: Fabrique Nationale d'Armes de Guerre (FN Herstal) Country of Origin: Herstal, Belgium Serial Number: 839xx Year of Manufacture: 1907 - 1909 Gauge: 12 Gauge Chamber: 2¾" (70mm) ONLY --- Condition Report This is an outstanding, well-preserved example of a very early production Browning Auto-5, the first successful semi-automatic shotgun design in history. The firearm presents in Excellent Antique Condition for its age of over 115 years, retaining a remarkable degree of its original finish and integrity. Receiver & Metalwork: The receiver is constructed of milled steel and retains most of its original blued finish, which has developed a smooth, patinated grey-brown character consistent with its age and careful handling. The surface is clean, with no significant pitting or active rust, only minor handling marks. All factory engraving, including the "BROWNING'S PATENTS" text and scrollwork, remains sharp and clearly legible. The serial number (839xx) is clearly visible and matches the era. The distinctive "Humpback" profile is crisp and untouched. Barrel: The original 26" (or 28") barrel is in excellent condition. The external blueing is strong with a vibrant, patinated sheen. The bore is bright and shiny with strong, sharp rifling (for a shotgun) and shows only minimal signs of use. All factory proof marks and inscriptions on the barrel are deeply stamped and fully legible, including: · FABRIQUE NATIONALE D'ARMES DE GUERRE HERSTAL-BELGIQUE · ACIER SPECIAL - 12 - CART. 2 3/4 · Belgian Proof Marks (Crown/ELG, PV, etc.), confirming its Belgian manufacture and safe proof-testing for 70mm shells. Stock & Forend: The firearm features its original, factory-fitted walnut stock and forend. The wood is sound and solid with no cracks, repairs, or significant dings. The original finish has a deep, warm, mellowed patina that can only be achieved through decades of gentle care. The checkering on the pistol grip and forend remains visibly clear and sharp, indicating very little wear. The fit of the wood to the metal is still excellent, as originally made by FN. Mechanical Function: This Auto-5 is reported to be in full working order and capable of precise shooting. The action cycles smoothly. The unique Browning-designed friction ring recoil system is present and correct, allowing for adjustment between light and heavy loads (though use with modern, standard-pressure 2¾" shells is always recommended with caution). Summary This is not merely a firearm; it is a pivotal piece of firearms history. As a pre-WWI Belgian-made Browning Auto-5 in such remarkable, all-original condition, it represents the pinnacle of early 20th-century craftsmanship. Its exceptional state of preservation, fully functional mechanics, and honest, untouched patina make it a highly desirable and valuable centerpiece for any serious collection of classic shotguns. It is a testament to the genius of John M. Browning and the legendary quality of FN Herstal.
