The Stevens Model 520 was a pump-action shotgun developed by John Browning and originally manufactured by the J Stevens Arms & Tool Company between 1909 and 1916.
 Stevens was sold to New England Westinghouse on 28 May 1915 and production of civilian firearms was greatly reduced.
 The company was renamed the "J Stevens Arms Company" on 1 July 1916 and New England Westinghouse used their manufacturing facility in Chicopee Falls, MA to produce Mosin-Nagant rifles under contract for the Russian Czar during World War I.
 After the war, Stevens was sold to Savage Arms on 1 April 1920 and full production of civilian firearms resumed.
 Under Savage ownership, Model 520 production continued until 1939 when it was replaced by the Model 520A which ended production in 1948.
 Stevens also further modified the design when they introduced the streamlined Model 620 in 1927.
 The Model 620 was internally similar to the Model 520 and was produced until 1939 when it was replaced by the Model 620A which ended production in 1955.
 This shotgun is a hammerless, pump action, take-down design with a tubular magazine which holds 5 shells.
 All models can also be slam fired: the shotgun has no trigger disconnector and shells can be fired one after the other simply by working the slide if the trigger is held down.
The .300 Savage cartridge is a rimless, .30 caliber rifle cartridge developed by the Savage Arms Company in 1920.
 It was designed to replace the less powerful .303 Savage in their popular Savage Model 99 lever-action rifle.
 Despite having a short case and a rather stumpy neck, the cartridge is capable of propelling a 150 gr bullet at over 2600 ft/s with an effective range of over 300 yards .
Stevens Arms was an American firearms manufacturer founded by Joshua Stevens in 1864 in Chicopee Falls, MA.
 The company introduced the .22 Long Rifle round and made a number of rifle, shotgun, and target pistol designs.
 By 1902 they were advertising themselves as "the largest producers of sporting arms in the world".
 They were purchased by New England Westinghouse on May 28, 1915 and again by Savage Arms on April 1, 1920.
 As a division of Savage, Stevens continued to produce firearms at their Chicopee Falls facility until 1960 when the plant was torn down and Stevens production was moved into other Savage facilities.
 Savage dropped the Stevens name in 1991 but revived it in 1999 and still uses it today for a number of its low cost rifles and shotguns.
The Savage Model 1907 is a semi-automatic pocket pistol produced by the Savage Arms Company of Utica, New York, from 1907 until 1920 in .32 ACP and from 1913 until 1920 in .380 ACP caliber.
 Although smaller in size, it is derived from the .45 semi-automatic pistol Savage submitted to the 1906-1911 US Army trials to choose a new semi-automatic sidearm.
 After several years of testing the Savage pistol was one of two finalists but ultimately lost to the Colt entry, which became famous as the Colt Model 1911.
 181 of these .45 ACP pistols were returned to Savage after the testing and sold on the civilian market.
The 5.6×52mmR cartridge was created by Charles Newton and produced by Savage Arms in 1912.
 It is also known as the .22 Savage High-Power and .22 "Imp", and is based upon the .25-35 Winchester cartridge necked down to accept a .227in/.228in diameter bullet.
 Its original loading was a 70 grain soft point bullet with a velocity of around 2700–2800 feet per second depending on the rifle.
The .250-3000 Savage is a rifle cartridge created by Charles Newton in 1915 and is also known as the .250 Savage.
 The name comes from its original manufacturer, Savage Arms and the fact that the original load achieved a 3000 ft/s (910 m/s) velocity with an 87 grain (5.6 g) bullet.
Savage Arms Company is an American firearms manufacturing company based in Westfield, Massachusetts, with a Canadian division located in Lakefield, Ontario.
 The company makes a variety of rimfire and centerfire rifles, as well as marketing the Stevens single-shot rifles and shotguns.
 They may be best known for the Model 99 hammerless lever-action rifle (no longer in production) and the very popular .300 Savage sporting cartridge, which was the parent case for the .308 Winchester cartridge.
 According to the ATF statistics for 2015, Savage is currently America's third largest rifle manufacturer behind Remington Arms and Sturm Ruger.
The .303 Savage is a rimmed, .30 caliber rifle cartridge developed by the Savage Arms Company in 1894 which was designed as a short action cartridge for their popular Savage Model 99 hammerless lever-action rifle.
 The cartridge was designed for smokeless powder at a time when black-powder cartridges were still popular.
 The .303 Savage round was ballistically superior to the .30-30 Winchester, but only marginally.
 The .303 Savage remained popular through the 1930s.
A lawyer and firearm enthusiast, Charles (Chas.)
 Newton's experiments with cartridge design led to the creation of the .22 Savage Hi-Power rifle cartridge which was adopted by the Savage Arms Corporation as a commercial firearm cartridge.
 This success was soon followed by the design of the .250-3000 Savage.
 At this period in time, Charles also experimented with wildcats based on the .30-06 Springfield case, most notably creating a forerunner of the .25-06 Remington.
 This cartridge was first introduced as the .25 Newton Special.
 There were probably no firearms produced in this caliber by Netwon.
 It soon evolved into the .256 Newton designed to use, at first, a 123 grain bullet followed by later upgrades to 129 grain and 140 grain bullets.
 Newton's premise was to use a large case for each caliber he developed in order for the larger powder charge to propel the bullet at high velocity resulting in effective terminal ballistics.
 Newton developed several calibers.
 The best known are the .22 Newton (90 grain bullet), .256 Newton, .30 Newton (180 grain bullet), .33 Newton (200 grain bullet), .35 Newton (250 grain bullet) and .40 Newton (300 grain bullet).
 From 1914 until the late 1920s, he entered into various endeavours to promote and sell rifles in his proprietary calibers.
The New England Westinghouse Company is a former division of Westinghouse Electric.
 It was founded in 1915 in East Springfield, Massachusetts.
 Its primary purpose was to fulfill a contract to produce 1.8 million Mosin–Nagant rifles for Czar Nicholas II of Russia during World War I.
 In order to produce the rifles, they purchased the J Stevens Arms & Tool Company in Chicopee Falls, MA on 1 July 1916 and acquired all its holdings which included firearms and tool manufacturing facilities, and the Stevens-Duryea automobile factory.
 They sold the tool manufacturing portion of Stevens and shut down production of Stevens-Duryea automobiles and civilian firearms.
 The remaining Stevens firearms facility was renamed the J Stevens Arms Company and its machinery was retooled to meet the Mosin–Nagant contract.
 After some 770,000 rifles had been produced, the Czar was deposed, the Russian government defaulted on the contract, and New England Westinghouse did not receive payment.
 The company entered hard times and started producing M1918 Browning Automatic Rifles at the former Stevens-Duryea factory that was originally constructed for car manufacturing in 1912.
 In 1920 they sold the J Stevens Arms Company to Savage Arms but kept the automobile factory for use producing commercial products for Westinghouse Electric.
 In 1921, the Stevens-Duryea factory was the location of the first broadcasts of WBZ (AM), the first commercial radio station in the United States.
