The "Yellow Boy" — Winchester's first model, successor to the Henry Rifle. The distinctive brass receiver (giving it the nickname) combined with Nelson King's improved magazine loading gate allowed loading from the side rather than the front. 17-shot capacity in the rifle configuration. Sold massively on the frontier and exported worldwide, earning the description "the gun that won the West." Type: Rifle Action: Lever-Action Caliber: .44 Henry Rimfire Capacity: 17 Year introduced: 1866, USA Weight: 80 oz Overall length: 43" Status: Discontinued Intended use: civilian, military, hunting
