Arisaka type 38

The Type 38 rifle Arisaka (三八式歩兵銃) was a bolt-action rifle that supplemented the Type 99 Japanese standard infantry rifle during the Second World War. The design was adopted by the Imperial Japanese Army in 1905 (the 38th year of the Meiji period, hence "Type 38") and served from then until the end of 1945.

History and development
The Imperial Japanese Army introduced the Type 30 rifle in 1897. However, the weapon had numerous shortcomings, which were highlighted by combat experience in the early stages of the Russo-Japanese War. These included bursting cartridges, a poorly designed lock in which excess gunpowder tended to accumulate, burning the face of the shooter, frequent misfires, jamming, difficulty in cleaning, and cartridge extraction. Major Kijiro Nambu undertook a redesign of the Type 30, which was introduced in 1906. Nambu reduced the number of parts making up the Type 30's bolt from nine to six and at that same time simplified manufacture and disassembly of the bolt without the need for tools. A dust cover was added because of experiences in the Russo-Japanese War that left rifles inoperable from dust. The weapon was produced in several locations:


 * Tokyo Arsenal from 1906 to 1932; 2,029,000 units (est.)
 * Kokura arsenal from 1933 to 1941: 494,700 units (est.)
 * Nagoya arsenal from 1932 to 1942: 312,500 units (est.)
 * Jinsen (in what is now Incheon) arsenal from 1942 to 1942: 13,400 units (est.)
 * Hoten (was called Mukden Arsenal before the Japanese took it over. In what is now Shenyang) arsenal from 1937 to 1944: 148,800 units (est.)

By 1940 more than three million Type 38s had been issued to the Imperial Japanese Army. However, shortcomings in the Type 38 design during the Second Sino-Japanese War led to the introduction of a further generation of rifles, designated the Type 99 rifle from 1939. This new rifle used the more powerful 7.7×58mm Arisaka cartridge already in use with the Type 92 heavy machine gun and the Type 97 light machine gun. However, not all units received the new weapon, and the mixture of types with incompatible cartridges led to considerable logistics issues during World War II.

Description and variant types
The Type 38 rifle used the 6.5×50mm Arisaka cartridge. This cartridge produces little recoil when fired. However, while on par with the Norwegian and Italian 6.5mm military cartridges of the time, the 6.5×50mm was not as powerful as several others in use by other nations. The Type 38 at 1280 mm was the longest rifle of the war, due to the emphasis on bayonet training for the Japanese soldier of the era, whose average height was 160 cm. The rifle was even longer when the 400 mm Type 30 bayonet was fixed. The Type 38 was fairly heavy, at about 4.25 kg.

Post-war inspection of the Type 38 by the U.S. military and the National Rifle Association found that the Type 38's receiver was the strongest bolt action of any nation's and capable of handling more powerful cartridges.

Type 38 carbine
Intended for use by cavalry, engineers, quartermasters and other non-frontline troops, the Type 38 carbine was introduced into service at the same time as the standard Type 38. Its barrel was 487 mm, overall length 966 mm, and weight 3.3 kg. The rifle lacked a bayonet. It was produced in a number of locations:
 * Tokyo Arsenal from 1906 to 1931; 210,000 units (est.)
 * Kokura arsenal from 1938 to 1941: 49,500 units (est.)
 * Nagoya arsenal from 1935 to 1942: 206,000 units (est.)
 * Hoten/Mukden arsenal from 1938 to 1944: 52,300 units (est.)

Type 38 cavalry rifle
In the late 1930s to the early 1940s, an unknown number of Type 38 rifles were converted into cavalry rifles at Nagoya Arsenal, that did all rebuilds of Type 38 and Type 44 rifles and carbines. The barrels were shortened to 635 mm from the standard 794 mm barrel and the stock shortened to match the barrel while the handguard retained its original length. The end result is a Type 38 which is similar in size to the Type 99 Arisaka. The designation as a "cavalry rifle" is unusual as at that time the cavalry branch was in decline and it is far more likely these rifles were issued to second line troops instead. There is no consistency to serial numbers or arsenal marks as the rifles were converted from existing stock. Although total production is unknown, it is estimated that approximately 100,000 were converted.

Type 44 carbine
Similar to the Type 38 carbine from the middle band back. The cavalry carbine is almost entirely different from the middle band forward with an under-folding bayonet, metal nosecap, stacking hook to the left side of the nosecap and wide front sight guards. This model was introduced in 1911. There are three variations of this rifle. Each variation based entirely on the nosecap size and the spacing of the nosecap screws. They have a unique storage compartment in the buttstock for a cleaning rod.

Type 97 sniper rifle
As with the standard Type 38, but with a rifle scope with 2.5x magnification, introduced in 1937. The scope was offset to allow loading by stripper clip and bolt handle slightly bent down. Some 14,000 were produced.

Chinese Six/Five infantry rifle
Chinese copy of the Japanese Type 38 at the Taiyuan Arsenal in the very late 1920s to early 1930s for the warlord of Shansi province, General Yen Hsi-shan. The receiver is marked 六五步槍 or "six-five rifle". Estimated to have been 108,000 made.

Type 918 rifle
These copies of the Type 38 rifles are believed to have been manufactured at the South Manchuria Army Arsenal (also known as the 918 Arsenal), but very little is known about them. Chinese sources state that these rifles were made in China for Japan, but for whom it is not known. It does not bear the Japanese Imperial Chrysanthemum, but instead has a heart symbol and under it written "918 Type" (九一八式). It is also not known if these were made before or right after the surrender of Japanese forces. It has an under-folding bayonet similar to the Japanese Type 44. The 918 stamped on top of the receivers stands for the date of September 18, 1931; the date of the Mukden Incident.

North China Type 19 carbine
A relatively crude copy of the Type 38 carbine that is believed to have been made mostly in the Chinese city of Tientsin and may have been intended for puppet troops. Unlike the other Type 19 that is a copy of the Type 30 carbine, but in 7.92×57mm Mauser, this Type 19 is chambered in the Japanese 6.5x50sr cartridge. Like the other Type 19, it also has a cherry blossom on the receiver and not the Japanese Imperial Chrysanthemum and also says "North China Type 19" (北支一九式). The 19 may mean the 19th year of Showa Era or 1944. The true military designation is unknown. Approximately 40,000 carbines are thought to have been produced.

Siamese Type 66 long rifle
Siam (Thailand) ordered 50,000 Type 38 rifles in 1924 from the Tokyo Army Arsenal chambered in their Type 66 8x52r cartridge. The receiver is marked with the Siamese Charkra with "Type 66" (แบบ ๖๖) written under it. Not only was the caliber changed, but the sights, bayonet and cleaning rod are different than the Japanese version. Almost all parts, including screws cannot be interchanged with the Japanese Type 38.

Thai Type 83 rifle
Unlike the Siamese Type 66 (แบบ ๖๖), this rifle is a standard Japanese Type 38 in 6.5x50sr that was sent as aid from Japan to Thailand in 1940. These were taken straight from assembly lines at Nagoya and Kokura arsenals, after the Japanese Imperial Chrysanthemum was canceled out by zeros along the petals. In Thailand they called it the Type 83 (แบบ ๘๓). These rifles were issued to second-line troops to free up rifles in their main caliber from front line duties for the Franco-Thai War. Later in the 1950s, some of these rifles had their barrels and stocks cut down to short rifle length with many of those being rechambered for .30-06 Type 88 cartridge and becoming Type Type 83/88s (แบบ ๘๓/๘๘). Very few of these rifles were imported into the United States because of the Gun Control Act of 1968 restricting former military arms from entering the country.

Thai Type 91 police carbine
Made after World War II, these carbines were made in Thailand at the Royal Thai Arsenals in Bangkok from Type 38 parts for a handy carbine for police. The stock and barrel was cut down. The stocks were cut out like a M1 carbine stock and used M1 carbine slings and oilers. Some bolts were turned down, some not. Some had the Royal Thai Police symbol stamped on the receiver with "91" (๙๑) stamped above it and some received the Siamese Charkra stamped on the receiver. They all retained their original Japanese caliber of 6.5x50sr.

Mexican Model 1913 rifle and carbine
Ordered in mid 1913 from the Huerta government in the standard Mexican military caliber, 7×57mm Mauser, for 50,000 rifles and later for another 25,000 carbines from the Tokyo Artillery Arsenal. They were made to fit the Mexican Mauser model 1895, 1902 or 1910 bayonets. In early 1914 the first 10,000-15,000 rifles arrived in Mexico, but the Japanese suspended, probably because Huerta had fled the country in mid-1914 and feared they would not be paid for the rest. In late 1914 or early 1915 Imperial Russia, desperate for arms, bought the remainder left in Japan which was either 35,400 or 60,000 rifles and carbines. The first few thousand rifles had three interlocking circles on the receiver, the rest had the Mexican crest under "Republica Mexicana".

Estonian KL .303
Estonian conversion of standard Type 38 to .303 British cartridge, intended for usage by second line troops of the Estonian Defence League. Total 24,000 rifles were rebored during 1929-1934.
