Context_1 : The Winchester Model 37 (M37) Single Shot Shotgun is an American firearm. It was in production from 1936-1963 with 1,015,554 units made. This model was developed by Winchester with a standard visible hammer action for many years. The Winchester Model 37 uses a top-cocking lever, breakdown type of action with an automatic shell ejector. The first M37 shotguns were delivered on February 10, 1936 according to factory records. Notably M37 shotguns were not serial numbered. Context_2 : The Winchester Model 21 is a deluxe side by side shotgun. The shotgun's initial production run from 1931 through 1960 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. Context_3 : The Stevens Model 77E was the most widely used shotgun of the Vietnam War. The Model 77E was a short-barreled pump-action shotgun known variously as the "trench" or "riot" shotgun. The Model 77E had noticeably shorter stocks than similar United State military shotguns built by Ithaca Gun Company, Remington Arms, and Winchester Repeating Arms Company. These short stocks were intended to accommodate South Vietnamese soldiers, and the Model 77E was the first United States combat shotgun equipped with a rubber recoil pad. Model 77E shotguns were Parkerized with sling swivels and wooden stocks. Receivers were marked "U.S." and "p" proofmarks appeared on both barrels and receivers. Context_4 : The .38-56 Winchester Center Fire cartridge was introduced in 1887 by Winchester for the Winchester Model 1886, and was also used in the Marlin Model of 1895. Production of Winchester Model 1886s chambered in this cartridge ceased in 1910 due to lack of demand, while most commercial production of the cartridge itself ceased in the 1930s. New production loaded cartridges and unloaded brass cases are rare, and are often created using reformed .45-70 brass. The cartridge was originally intended to outperform the similar .38-55 Winchester, but in reality had very similar ballistics despite using more gunpowder. Context_5 : The Winchester Model 1912 (also commonly known as the Model 12, or M12) is an internal-hammer, pump-action, shotgun with an external tube magazine. Popularly named the "Perfect Repeater" at its introduction, it largely set the standard for pump action shotguns over its 51-year high-rate production life. From August 1912 until first discontinued by Winchester in May 1964, nearly two million Model 12 shotguns were produced in various grades and barrel lengths. Initially chambered for 20 gauge only, the 12 and 16 gauge versions came out in 1913 (first listed in the 1914 catalogs), and the 28 gauge version came out in 1934. A .410 version was never produced; instead, a scaled-down version of the Model 12 known as the Model 42, directly derived from scaled drawings of the Model 12, was produced in .410. Context_6 : The .45-60 Winchester is a centerfire rifle cartridge intended for 19th-century big-game hunting. Nomenclature of the era indicated the .45-60 cartridge contained a 0.45 in diameter bullet with 60 gr of black powder. Winchester Repeating Arms Company shortened the .45-70 government cartridge to operate through the Winchester Model 1876 rifle's lever-action. The Colt Lightning Carbine and the Whitney Arms Company's Kennedy lever-action rifle were also chambered for the .45-60. These early rifles' advantage of faster loading for subsequent shots was soon eclipsed by the stronger and smoother Winchester Model 1886 action capable of handling longer cartridges including the popular full length .45-70. The .45-60 and similarly short cartridges designed for the Model 1876 rifle faded into obsolescence as 20th-century hunters preferred more powerful smokeless powder loadings of cartridges designed for stronger rifles. Winchester production of .45-60 cartridges ended during the great depression. Context_7 : The Browning Automatic 5, most often Auto-5 or simply A-5, is a recoil-operated semi-automatic shotgun designed by John Browning. It was the first successful semi-automatic shotgun design, and remained in production until 1998. The name of the shotgun designates that it is an autoloader with a capacity of five rounds, four in the magazine and one in the chamber. Remington Arms sold a variant called the Remington Model 11 that was nearly identical but lacked the magazine cutoff found on the Browning. Context_8 : The FN TPS ("Tactical Police Shotgun") was a pump-action shotgun designed and manufactured by FN Herstal. It was based on the Winchester Model 1300 and used many similar features such as the ported barrel. It also had many modern features including an adjustable stock, pistol grip, adjustable sights and, MIL-STD-1913 Picatinny rail. The TPS features an M16A2 style front and rear sight. The sights are adjustable for both elevation and windage. Context_9 : The .40-60 Winchester is a centerfire rifle cartridge intended for 19th-century big-game hunting. Nomenclature of the era indicated the .40-60 cartridge contained a 0.40 in diameter bullet with 60 gr of gunpowder. Winchester Repeating Arms Company necked down the .45-60 Winchester cartridge to hold a bullet with improved ballistics for the Winchester Model 1876 rifle. The lever-action Model 1876's advantage of faster loading for subsequent shots was eclipsed two years later by the stronger and smoother Winchester Model 1886 action capable of handling longer cartridges with heavier bullets. The .40-60 and similarly short cartridges designed for the Model 1876 rifle faded into obsolescence as 20th-century hunters preferred more powerful smokeless powder loadings of cartridges designed for stronger rifles. Winchester production of .40-60 cartridges ended during the great depression. Context_10 : The Winchester Model 1911 SL Shotgun was a self-loading, recoil-operated shotgun produced by the Winchester Repeating Arms Company from 1911 to 1925. It was Winchester's first autoloading shotgun, but design flaws kept it from providing competition for the autoloading shotguns made by Remington Arms and Browning Arms Company. fact_1 :  It was Winchester's first autoloading shotgun, but design flaws kept it from providing competition for the autoloading shotguns made by Remington Arms and Browning Arms Company. fact_2 :  It was the first successful semi-automatic shotgun design, and remained in production until 1998. Question: The Winchester Model 1911 SL Shotgun competed against a shotgun that remained in production until when?
Output: 1998
