7.7 Jap Rifle Serial Numbers
By Edward J. Hoffschmidt
- Successor to the Type 38 rifle. Chambered in 7.7×58mm Type 99, later rimless variants of the Type 92 and 97 cartridges also usable. Designed in 1939, then produced and fielded from 1941 to 1945, the Type 99 was the most common Imperial Japanese service rifle of World War II and second most produced imperial rifle with 2,500,000 built.
- Few guns have been as maligned as the Japanese Model 1905 (Type 38) cal. During the early stages of World War II, ill-informed observers were calling the gun a piece of junk. Cartridge was considered totally inadequate for military use. Few correspondents took the time to find out how good the gun and cartridge really.
- Also, The serial number and the bolt with the last three or four digits of the serial number indicates they were matched at the factory or at ordinace and should be head spaced correctly. Also, If the blue finish is good or indicates that it was a good deep blue originally, it was an early rifle and well made.
- Model 30 rifles & carbines and Naval Model 35 rifles have bolts that were originally stamped with the weapon’s assembly number represented by a single Japanese character followed by up to three Arabic numbers. No examples have surfaced which were overhauled and bolts matched by the last three digits of the serial number as is the typical.
Few guns have been as maligned as the Japanese Model 1905 (Type 38) cal. 6.5 mm. rifle. During the early stages of World War II, ill-informed observers were calling the gun a piece of junk. The 6.5 mm. cartridge was considered totally inadequate for military use. Few correspondents took the time to find out how good the gun and cartridge really were.
I'm not entirely certain but. Jap rifles were Chambered either in 6.5x50 or 7.7x58, none where 6.6, if it did measure out to that then you would probably have to reload using.268 diameter bullets(6.5 carcano) rather than 264(all other 6.5s that I know of). Utilized as part of a: JAPANESE ARISAKA 7.7 mm MILITARY TYPE 99 RIFLE. This piece is classified as a'Veteran Bring Home' as evidenced by the ground off Mum and Japanese model-type designation. Stampings on the left side indicate the arsenal marks for: TOKYO JUKI KOGYO(SEE PHOTO) Serial number on left side: 42875 Additional inspector and other. JAPANESE ARISAKA TYPE 99 7.7 X 58MM RIFLE GI#: 101547982 THIS TYPE 99 ARISAKA IS SERIAL # 91121. IT IS CHAMBERED FOR THE 7.7 X 58MM ARISAKA CARTRIDGE.
The Arisaka is basically a modified Mauser. It was developed under the supervision of Col. Nariaki Arisaka, Superintendent of Tokyo Arsenal, and officially designated as the Type 38 (1905). Since the rifle is basically a Mauser, it has inherent safety features. The Arisaka is designed to handle gases from a ruptured case or primer. There are 2 gas escape holes in the top of the receiver and a large combination safety catch and gas shield to divert gases and brass particles away from the shooter's face. The bolt has large, solid, front locking lugs and the bolt handle engages a cut in the receiver and thus acts as a third or safety lug. The bolt has another lug about Vx' behind the left front locking lug which performs a number of jobs. It serves as a guide rib to prevent the bolt from jamming when the locking lugs pass through the section of the receiver cut away for clip loading. It also acts as a bolt stop. Its most important function is to cam the ejector into the path of the bolt. Unlike most Mausers, the ejector is not spring-operated, but rather it pivots on a separate screw; when the bolt is opened and pulled back, the bolt lug strikes the rear of the ejector, camming it into the bolt cut in the receiver.
The stock construction is unusual. The butt is made in 2 pieces dovetailed together. This method allows the use of smaller blanks and a stronger grain direction through the pistol grip area. The 2 steel tangs extending back from the action strengthen the pistol grip area even more.
Although the Japanese cal. 6.5 mm. Arisaka rifle is an excellent military arm, it has a number of faults from

The cal. 6.5 mm. Arisaka was made in a variety of sizes and models, ranging from the carbine to the long rifle. Early cal. 6.5 mm. rifles were as finely
ITo remove assembled bolt (6), first pull it all the way to rear. Then pull bolt stop (8) out to clear stop lug on bolt. Unlike other Mauser rifles, it is not necessary to engage safety in order to disassemble bolt outside receiver
2 To disassemble bolt, hold it as shown and push safety catch (1) in as far as it can go. Rotate bolt Va-turn and ease out safety catch, firing pin (3), and firing pin spring (2). When reassembling, sear notch must be seated in shallower notch in bolt so that firing pin does not protrude.
Then push in safety catch
3 Extractor (5) is attached to bolt in typical Mauser style. To remove it, rotate extractor until small guide rib which rides in groove in front end of bolt is free of groove. Push extractor forward until it snaps free of extractor collar finished as the average sporter.
Shortly before the beginning of World War II, the cal. 6.5 mm. rifle was superseded by the Type 99 (1939) cal. 7.7 mm. rifle.
While the Type 99 has basically the same action as the Type 38, the design was simplified and the majority of parts are not interchangeable with those of the Type 38 rifle.
4 To empty magazine without running cartridges through gun, release floor-plate (25) by depressing floorplate release (26) in as far as it will go. Floorplate, magazine spring (20), and follower (19) are now detached from magazine
5 To remove bolt stop screw (9), action must be removed from stock. To remove bolt stop spring (7), rotate it 90° as shown and pull it free of bolt stop (8)
6 All Japanese cal. 6.5 mm. rifles are equipped with a full-length cleaning rod for threading to a handle in the soldier's cleaning kit. To remove cleaning rod (36), push in on long spring that retains front band (35). To remove band (35), remove rod and depress spring as far as possible, and then gently drive off front band ■

A friend of my dad’s recently passed away. His widow has a Japanese Type 99 rifle I am interested in buying. As best I can tell it is a matching 6th series Nagoya with intact mum, and aircraft sights, no dust cover.
The stock has the standard complement of dings, scratches, and character gouges you would expect to find on a common condition Arisaka. The rifle is covered in a layer of dust and cannot even see down the bore as it is full of cobwebs. Some of the blue metal finish is there under the dust but much of it is a brown patina now.
I want to buy it from her fair, but not hurt myself either. I need a type 99 for my collection. I would like to use it to shoot for vintage military matches if the bore turns out to be decent, but I don’t want to sink a ton of money in it if it is not.
I have some numbers in mind but wanted to put it out there to gain a general consensus from you guys in order to confirm my thoughts.
I know you cannot see this rifle to give a qualified value, and it is kind of a pig-in-a-poke not being able to ascertain the condition of the bore, but given that; what is your general gut feeling of what I should offer her?
I need to make her an offer tomorrow. Thanks in advance for your help.
