The Lewis Light Machine Gun was designed by Isaac Newton Lewis in 1911, based on earlier designs by Dr. Samuel McClean. The gun was designed in the United States, but the US military initially rejected the gun. Frustrated, Lewis retired and moved to Belgium in 1913 to start his own arms company, Armes Automatiques Lewis, from which he produced a small number of guns for Belgian government. In 1914, the Birmingham Small Arms Company in England paid Lewis royalties to begin manufacturing the gun for the British government, who adopted the gun shortly before the outbreak of the war. After England's adoption, the United States soon adopted it as well. The US guns made by Savage Arms were chambered in .30-06 Springfield and the guns made by BSA and AAL were chambered in .303 British. The gun was almost immediately pressed into service in the summer of 1914 when German forces invaded Belgium. The guns were used extensively in WWI as the primary light machine gun of the English and Belgian armies. They would go on to see service with the English in WWII as a secondary light machine gun. They were officially dropped from military service in 1946. Over 200,000 Lewis Guns were made in its 35-year lifespan.
The Lewis Gun is a gas-operated open-bolt machine gun with a mechanically indexed pan magazine. It uses a long-stroke gas piston to operate the bolt and index the pan. The bolt is locked to the rear in normal operation, and linked to the gas piston through a cam track. The mainspring puts tension on the gas piston with a rack-and-pinion gear powered by a circular torsion spring (similar to a clock spring). When the trigger is pulled the bolt moves forward, picking up a cartridge from the feed tray on the top of the receiver and chambering it. When the locking lugs on the bolt clear the locking surfaces, the firing pin is allowed to continue forward in the bolt's cam track, rotating it into the locked position and firing the cartridge. The bullet moves down the barrel, and eventually reaches the gas port. High-pressure gas is vented into the gas tube, where it pushes backward on the gas piston. By the time the gas piston moves rearward far enough to cam the bolt back open, the bullet has left the barrel and pressure has dropped to a safe level. As the bolt now moves backward due to the recoil of the firearm, a lug on the top of the bolt cams the indexing plate to the left, which simultaneously rotates the pan magazine by one position and loads a new cartridge from the pan into the feed tray. When the bolt reaches the end of its travel, the old case is ejected and the process repeats itself until the trigger is released.
Another unique feature of the Lewis Gun is the aluminium cooling shroud which was standard on the infantry model. Early machine guns were prone to overheating with extensive use, so they needed some way to dissipate the heat from the barrel to avoid damaging it and negatively impacting accuracy and power. Most machine guns in the WWI era did this with a heavy water-cooling system which dissipated the heat into a water tank around the barrel. However, Lewis came up with an ingenious way to air-cool the barrel with much lighter materials, making a man-portable machine gun capable of high volumes of fire without overheating possible. He did this by surrounding the barrel and gas tube with aluminium radiator fins to act as a heat sink. A metal shroud was then fitted over the radiator fins, which has a constriction in front of the barrel. This constriction creates suction at the rear of the shroud when the high pressure muzzle blast is forced through the constriction - a phenomenon known as the Venturi effect. As air is sucked through the shroud by the Venturi effect, it radiates the heat away from the aluminium fins.
The locking mechanism of the Lewis Gun is nothing special. Gas-operated rotating-bolt firearms are extremely common today, used in some of the most common autoloading rifles such as the Colt AR-15 and AK-pattern guns. However, the top-feeding pan magazine is a very unique operating system only found on a few other guns. Only 2 other pan-magazine firearms were produced in any significant number, the Russian DP-28 LMG and the American-180 SMG. Luckily, the Silenced .22 SMG in the vanilla game is an American-180, so the animations line up very well with the Lewis Gun's operating system.
I originally intended to put this gun in Fallout 4, but it has taken so long to make this thing I might as well put it in New Vegas too. When I do get around to putting it in Fallout 4, it will have custom animations and a few more attachments and accessories. For now I'm working on smaller projects.

Important Info!
The model is very large and fills half of the screen when using Asurah's animation pack. I recommend either using a different set of animations or an FOV higher than default. Even with vanilla animations the gun looks best with an FOV of 90 or so.
Also, you need a pretty good PC if you want to use the 4K textures with an ENB. If you experience crashes or lagging, use the 2K textures.

The gun and its mods are located in a rocky chasm on the east side of the Colorado River, near the base of the Hoover Dam. The location is due east of Ranger Station Delta. It is also sold by the Gun Runners.
Alternatively, the gun can be obtained via console commands. The base ID is "xx000ade", where "xx" is the mod's position in your load order.
The full stock is "xx000adf".
The cooling shroud is "xx000dbe".
