"*MONUMENTAL CLAYTON NELSON CUSTOM FARQUHARSON SINGLE SHOT DANGEROUS GAME RIFLE WITH CASE. SN 49. Cal. 700 Nitro express. This massive creation, by a gunsmith renown for a kaleidoscope of interesting and unusual guns, weighs over 16 pounds, barely ample weight for a cartridge that develops almost 9000 foot pounds of energy at muzzle. Consignor states that “Clayton Nelson built the barrel action. His son Lars did the sight work, stocked the rifle, and completed it. Engraving was done (and sign) by James White, Wasilla, Alaska. Recoil pad elephant hide.” This fine rifle has 28" tapered round bbl with 4-1/4" reinforced portion at breech which measures 1.6" in diameter. Muzzle diameter is 1.03. Bbl is fitted with well filed and nicely matted quarter rib with scroll engraved accents to attaching screws. One standing, two folding leaf express sight with inlaid gold lines is marked for 25 and 50 yards, and is dove-tailed through raised ovoid island at front portion of rib. Silver bead front sight with flip-up ivory night sight, is longitudinally dovetailed into ramp base which matches transition of quarter rib. There are one inch triangles of scroll engraving either side of front sight base at muzzle, and rear of quarter rib at breech. Left side of breech reinforce is inlaid in gold with “.700 Nitro Express”. Wide sling loop is milled integrally into bottom of bbl. This fine bbl is mated to custom made over sized tang safety Farquharson action which is 1.79" wide and over 3" high. Action is coin finished. Trigger plate is rust-blued. Trigger is heat-blued. Operating lever is case hardened. Sides of action are engraved with beautifully cut shaded open scroll, framing Bulino vignettes of big game; a quartering cape buffalo in thick cover on right side, and huge tusker in savanna on left. Engraver’s signature “J. White” is on right side of receiver at lower right over scroll. Trigger plate is milled and filed in classic Farquharson manner. SN is inlaid in gold on lower tang which extends to engraved steel grip cap. Blued tang safety button is nicely checkered, and “Safe” is inlaid in gold. Exceptionally fine, dense, beautifully marbled and figured Circassian walnut buttstock measures 14-7/8" over black elephant hide covered pad. Stock features large classic shadow line right hand cheekpiece, sling swivel eye set into boss on toe line of stock, and cleanly cut 20 LPI point pattern checkering with mullered borders. Matching forend attaches to recoil boss on bbl with screw through engraved diamond escutcheon, and features wrap-around checkering, borderless checkered pattern in front of action transition, and large horn tip. Drop at heel: Approx 2-3/8", drop at comb: Approx 2". Weight: 16 lbs. 4 oz, LOP 14-7/8".

Covers are oak with brass knobs, and contain 3 cartridges, cleaning equipment, sling, and the key. Plaque is mounted inside with information on 700 H & H cartridge. CONDITION: Excellent, nearly as new. There is some slight discoloration on left side of action in the area of the elephant’s forehead. There are one or two very minor marks on stock. Case is excellent. An exceptional rifle in the biggest express caliber of all time. 4-41122 MGM8 (25,000-35,000)"
