This Sterlingworth is a Philadelphia-era gun marked "STERLINGWORTH FLUID COMPRESSED STEEL" on the barrels with the address "MADE BY A.H. FOX GUN CO. PHILA. PA. U.S.A." on the rib.
It carries the solid matted top rib and single front bead typical of the period, paired with 30-inch steel barrels and a two-round capacity.
The action is a break-action, hammerless design with double triggers, delivering the traditional A.H. Fox side-by-side configuration. The water table bears the patent legend including "JAN. 16, 1906," consistent with early production features.
Stocking is classic Fox: a pistol-grip walnut buttstock with checkering and a matching checkered splinter forend. An aftermarket Kick-EEZ recoil pad has been fitted, setting the length of pull at 14.0 inches while maintaining a comfortable shooting profile.
Factory-applied simple line/border engraving accents the frame and trigger guard. The gun shows matching serial numbers on the water table, forend iron, barrel lug, and trigger-guard tang, reinforcing the originality of its major components. Made in the United States, this example reflects the hallmark build quality of the Philadelphia A.H. Fox era.
