COLLECTIBLE FIREARMS

Atlas Collectible Firearms is profoundly honored to present an extraordinary, museum-tier masterpiece of Winchester lever-action history: an original 1999-manufactured Winchester Model 1866 "Yellow Boy" Deluxe Grade VI lever-action rifle chambered in .44-40 Winchester. Manufactured in an exceedingly limited run of fewer than 100 units worldwide, this magnificent Grade VI offering features a 24-inch polished blued octagonal barrel with full-length tubular magazine, custom gold-inlaid barrel bands, and a lavishly hand-engraved, bright gold-plated receiver. Carrying serial number 00078ZN66F sharply stamped on the frame, factory records confirm this rifle as unit #78 of this ultra-exclusive limited series, standing as a crown jewel investment piece for the most discerning Winchester purists.
Highlighting its master grade execution, the polished gold-plated receiver displays intricate, full-coverage scroll engraving enclosing detailed game scenes, perfectly complemented by delicate gold inlaid scrollwork extending along the breech top and barrel flats. Stocked in an exhibition-quality Grade VI American walnut furniture set featuring intense, high-contrast figure clarity, satin finish, and a polished brass crescent buttplate, this rifle arrives 100% complete with its original factory packaging and paperwork suite. The comprehensive grouping includes the original factory shipping container with its matching end label explicitly confirming "M66 DLX RIFLE OCT 24"", "44-40 Win.", and serial number 00078ZN66F, alongside the original Model 1866 owner's manual and factory promotional inserts.
Preserved in 100% New Old Stock (NOS) pristine unfired condition throughout, this Grade VI Model 1866 displays zero operational wear, handling marks, or finish blemishes across its gold and blued steel surfaces. The exhibition walnut stock set remains immaculate, showcasing breathtaking wood grain depth free of impressions, scuffs, or lacquer imperfections. Mechanically, the hand-fitted lever action functions with smooth, vault-tight precision and crisp trigger engagement, while the 24-inch octagonal barrel preserves a 100% mirror-bright, unblemished bore with razor-sharp rifling lines from chamber to muzzle.
