FROM WIKIPEDIA
The Winchester Model 21 is a deluxe side by side shotgun. The shotgun's initial production run from 1931 through 1959 yielded approximately 30,000 guns. Winchester Repeating Arms Company ceased the main production line of this shotgun in 1960 and the Model 21 was sourced to the Winchester Custom Shop until the gun's retirement in 1991. New Winchester Model 21 production continues under license to Connecticut Shotgun Manufacturing Company.
