Manufactured in 1940 or 1941 and subsequently upgraded by Simmons Gun Specialties Inc., innovators of ventilated ribs and other shotgun improvements established in Kansas City, Missouri, in 1945 and located in Olathe, Kansas, since the mid-1960s. The rib has a bright steel bead front sight, straight serrations on top, and is marked "SIMMONS GUN SPECIALTIES, INC., OLATHE, KANSAS" on the left side near the breech. The barrel has the factory two-line, three-block legend including the "-FOR SHOT ONLY-" marking. No proof is visible on the breech end of the barrel. The frame has the proof offset to the left at the breech and wavy line serrations on top. "S" with a chevron above and below is on the left side of the trigger guard by the slide release, and the matching serial number and a faint "W" are on the bottom of the action. The forearm has seventeen grooves on each side, and the smooth pistol grip stock has some attractive tones and a checkered steel buttplate. Included with the rifle is a factory box hand numbered to the gun and has a golden Simmons Gun Specialties label on the other end and contains two Winchester pamphlets. This rifle is pictured and identified in Ned Schwing's "Winchester Slide-Action Rifles, Vol. II" on page 46.
