It is a semi-automatic rifle used by the German army during World War II, designed and produced by the German company Walter. Mass production began in 1942 and officially entered service in 1943. Using 7.92 × 57mm Mauser rifle ammunition, with a 10 round magazine, the effective range can reach 800 meters. Its design draws on the experience of G41 rifle, improves the air guiding system, enhances reliability and production efficiency. Technically equivalent to the M1 Garand rifle, but due to production capacity and material limitations, the output is lower. In the later stages of the war, due to resource constraints, the production process of G43 was simplified. It is an excellent semi-automatic rifle.

It is a common firearm in the 18th century, which uses flint or flint pieces as ignition devices. When the trigger is hit by a hammer, sparks are generated, igniting the gunpowder. Ammunition needs to be manually reloaded and loaded through the barrel opening, including gunpowder, pellets, and paper pads. The paper pads provide a sealing effect to ensure that gunpowder and pellets are tightly compressed inside the barrel. In combat, these weapons are usually only used for single shot shooting because the loading method is very slow and there is usually no time to reload. Therefore, soldiers who have fired have to pull out their swords or knives, or if they cannot reload them in time, use pistols as sticks.

It is a work from the late 19th century and is currently housed in a museum in the New Songki area. Composed of two vertically arranged gun barrels, the bottom of the barrel is decorated with geometric floral patterns and the manufacturer's logo "SCHLEGELMILCHINOEDENBURG". The barrel starts from an octagon about 7 centimeters long, gradually becomes hexagonal, and finally becomes circular. The outer part of the gun barrel is also decorated with carved floral patterns. The trigger is surrounded by a brass trigger guard that extends all the way to the top of the stock. On the trigger guard, there are carved oak leaves and the initials "C...".

M38, abbreviated as M38, is a new type of carbine designed and finalized by the Soviet Union in 1938 based on the M1907 carbine. As a shortened version of the M1891/30 rifle, it is mainly designed for the needs of non frontline combat units such as cavalry, artillery, and messengers, to meet their demand for shorter and lighter weapons. The overall length of the rifle is the same as the M1907 carbine, without a bayonet, but it maintains a high degree of consistency with the M1891/30 rifle in other aspects, such as a guard sight, metric gauge, and circular section receiver. The range of the gauge is relatively short, from 100 meters to 1000 meters, with increments of 100 meters.

It is an early firearm that originated in 16th century Europe and is the successor to the matchlock gun. By using flint and gunpowder to ignite bullets, they can be fired. The working principle is that when the trigger is pulled, the flint will rub against the gunpowder to produce sparks, igniting the gunpowder loaded in the barrel and pushing the bullet out. Compared to previous matchlock guns, it is more reliable because it does not rely on a continuously burning matchlock to ignite gunpowder, reducing the risk of ignition failure caused by wind or humid weather. The emergence of flintlock guns greatly increased the firepower and range on the battlefield, while also reducing the exposure time of soldiers when loading ammunition.
