Question: The Rieder Automatic Rifle was a model made by the company that created firearms for the forces of what country?

full_context: Document 1: Howell Automatic Rifle: The Howell Automatic Rifle an automatic conversion for the Lee–Enfield rifle. The weapon was reliable but unergonomic for the user as the force of the recoiling bolt interfered with handling. Similar conversions were the South African Rieder and Charlton of Australian/New Zealand origin which had full automatic capability.
Document 2: Lee–Metford: The Lee–Metford rifle (a.k.a. "Magazine Lee–Metford", abbreviated "MLM") was a bolt action British army service rifle, combining James Paris Lee's rear-locking bolt system and detachable magazine with an innovative seven groove rifled barrel designed by William Ellis Metford. It replaced the Martini–Henry rifle in 1888, following nine years of development and trials, but remained in service for only a short time until replaced by the similar Lee–Enfield.
Document 3: Ross rifle: The Ross rifle was a straight-pull bolt action .303 inch-calibre rifle produced in Canada from 1903 until 1918.
Document 4: No.8 rifle: The Rifle, Number 8 (commonly referred to as the Number 8 Rifle) is a bolt-action .22 calibre version of the Lee–Enfield designed for British Army target shooting. They are simple hand-fed rifles and were originally designed to be used by military marksmen firing in civilian competitions , before being turned over to the cadet forces. Currently, the Number 8 is used by the British cadet services as a basic target rifle. Some examples are in civilian ownership worldwide, especially following the disposal by the New Zealand cadet forces of their Number 8 and Number 9 rifles at auction.
Document 5: Gewehr 98: The Gewehr 98 (abbreviated G98, Gew 98 or M98) is a German bolt-action Mauser rifle firing cartridges from a 5-round internal clip-loaded magazine that was the German service rifle from 1898 to 1935, when it was replaced by the Karabiner 98k. The Gewehr 98 action, using stripper clip loading with the powerful 7.92×57mm Mauser cartridge, introduced advanced infantry weapon features rapidly adopted in the Anglo-American Pattern 1914 Enfield/M1917 Enfield and the Japanese Arisaka Type 38/Type 99. The Gewehr 98 replaced the earlier Gewehr 1888 rifle as the German service rifle, first saw combat in the Boxer Rebellion, and was the main German infantry service rifle of World War I. The Gewehr 98 saw further military use by the Ottoman Empire and Nationalist Spain. Many have been converted to sporting use.
Document 6: Charlton Automatic Rifle: The Charlton Automatic Rifle was a fully automatic conversion of the Lee–Enfield rifle, designed by New Zealander Philip Charlton in 1941 to act as a substitute for the Bren and Lewis gun light machine guns which were in chronically short supply at the time.
Document 7: Sieg automatic rifle: The Sieg automatic rifle was a bullpup automatic rifle designed by Chief Gunner's Mate James E. Sieg of the US Coast Guard. The weapon was chambered in the .30-06 round, fed from 20 round magazines and capable of firing around 650–700 RPM on full automatic. A two-finger double trigger selected between semi- and full-automatic fire. The barrel came with a unique muzzle compensator that could be turned off for use with a flash hider or grenade launcher without interfering when also installing a bayonet. Recoil gently threw the barrel of the Sieg rifle downward, not upward. When tested at Fort Benning, it had effective results. The compensator was extremely effective; it also enabled the user to fire the rifle with one hand.
Document 8: Karabiner 98k: The Karabiner 98 kurz (] ; "carbine 98 short", often abbreviated Kar98k or K98k) is a bolt-action rifle chambered for the 7.92×57mm Mauser cartridge that was adopted on 21 June 1935 as the standard service rifle by the German "Wehrmacht". It was one of the final developments in the long line of Mauser military rifles. Although supplemented by semi- and fully automatic rifles during World War II, it remained the primary German service rifle until the end of the war in 1945. Millions were captured by the Soviets at the conclusion of World War II and were widely distributed as military aid. The Karabiner 98k therefore continues to appear in conflicts across the world as they are taken out of storage during times of strife.
Document 9: Sterling submachine gun: The Sterling submachine gun is a British submachine gun. It was tested with the British Army in 1944–1945 as a replacement for the Sten but it did not start to replace it until 1953. It remained in use until 1994, when it was phased out as the L85A1 assault rifle was phased in.
Document 10: Lee–Enfield: The Lee–Enfield is a bolt-action, magazine-fed, repeating rifle that was the main firearm used by the military forces of the British Empire and Commonwealth during the first half of the 20th century. It was the British Army's standard rifle from its official adoption in 1895 until 1957. . It is often referred to as the "SMLE," which is short for the common "Short Magazine Lee-Enfield" variant.
Document 11: Leader Dynamics Series T2 MK5: The Leader T2 MK5 Series weapons were chambered for the 5.56×45mm NATO cartridge and manufactured by Leader Dynamics of Smithfield, NSW, Australia (1978-1982/1983). The Leader was the brainchild of weapons designer Charles St. George. It was originally a contender for a 5.56 mm Australian military service rifle to replace the then-issued Lithgow L1A1-F1 SLR and Colt M16A1 rifles. What was unique about this endeavor was that Australia had never designed or manufactured its own commercial gas-operated semi-automatic rifle. The rifle was abandoned when the Steyr AUG was adopted for use by the Australian military.
Document 12: Rieder Automatic Rifle: The Rieder Automatic Rifle was a fully automatic Lee–Enfield SMLE rifle conversion of South African origin. The Rieder device could be installed quickly with the use of simple tools. A similar weapon of New Zealand origin was the Charlton Automatic Rifle.
Document 13: Bolt action: Bolt action is a type of firearm action in which the weapon's bolt is operated manually by the opening and closing of the breech (barrel) with a small handle, most commonly placed on the right-hand side of the weapon (for right-handed users). As the handle is operated, the bolt is unlocked, the breech is opened, the spent cartridge case is withdrawn and ejected, the firing pin is cocked (this occurs either on opening or the closing of the bolt, depending on design), and finally a new round/cartridge (if available) is placed into the breech and the bolt closed. Bolt-action firearms are most often rifles, but there are some bolt-action shotguns and a few handguns as well. Examples of this system date as far back as the early 19th century, notably in the Dreyse needle gun. From the late 19th century, all the way through both World Wars, the bolt-action rifle was the standard infantry firearm for most of the world's militaries.
Document 14: Squad automatic weapon: A squad automatic weapon (SAW, also known as section automatic weapon or light support weapon) is a weapon used to give infantry squads or sections a portable source of fully automatic firepower. Weapons used in this role are often selective fire rifles, usually fitted with a bipod and heavier barrel to perform as light machine guns. Squad automatic weapons usually fire the same cartridge as the assault rifles or battle rifles carried by other members of the unit. This reduces logistical requirements by making it only necessary to supply one type of ammunition to a unit. Squad automatic weapons are light enough to be operated by one person, as opposed to heavy machine guns such as the M2 Browning, which fire more powerful cartridges but require a crew to operate at full effectiveness.
Document 15: M1 Garand: The M1 Garand is a .30 caliber semi-automatic rifle that was the standard U.S. service rifle during World War II and the Korean War and also saw limited service during the Vietnam War. Most M1 rifles were issued to U.S. forces, though many hundreds of thousands were also provided as foreign aid to American allies. The Garand is still used by drill teams and military honor guards. It is also widely used by civilians for hunting, target shooting, and as a military collectible.
