A contract was signed ordering tens of thousands of Type I rifles (the exact quantity is unclear – most sources say 60,000, but the serial number range would suggest more than double that number). The rifle was based on a Carcano receiver and bolt, but otherwise configured like a Type 38 Arisaka. Model: Arisaka, Type 99 Serial Number: 60425 Year of Manufacture: 1939 - 1943 Caliber: 7.7x58mm (7.7 Jap) Action Type: Bolt Action, Internal Magazine Markings: There is no visible import mark. The top of the receiver has had its “chrysanthemum” (the Imperial ownership seal) defaced with a large “X”.

Nambu World: Arisaka Type 2 Paratroop Rifle

The Type 2 Paratroop rifle is basically a take-down version of the Type 99 Arisaka rifle. It fires the 7.7mm X 58 Arisaka cartridge. The Japanese experimented with several versions of paratroop rifles, including ones with folding stocks and an interrupted thread-style take-down before settling on this one, which has a screw-in wedge that holds the two halves together (the system will be described in great detail below with close-up photos). The Type 2 is the only paratroop rifle that was produced in any real quantity (i.e. more than a few hundred), and even it is rare, with only about 21,200 known to have been produced. The model designation comes from the year based on the Japanese system that counted from the date of the mythological founding of the Japanese Empire by Emperor Jimmu in 660 B.C. By this system, the Western year 1942 when the gun was adopted was 2602, with the 'two' becoming the model designation. Actual production began in late 1943. I was very lucky to acquire this rifle in late 2008 from the daughter of the U.S. veteran who brought it back. It came with the 'bring back' document and a few other items that he brought back. These are shown further down the page together with a brief summary of the soldier's story. The gun is all matching, and although the 'mum' has been ground, it appears to be in unissued condition. Immediately below is a view of the left side. Overall length is 1120mm(44-1/8'). The barrel is 649mm (25-1/16') when measured as required by Canadian law (rod down the barrel with the bolt closed).

The Japanese did not make very extensive use of paratroopers and development of specialized weapons for them also lagged. According to the Fred Honeycutt book Military Rifles of Japan, (pp. 134-135), the experiences of the airborne attack on Palembang in Sumatra, Dutch East Indies, February 13-15, 1942 may have provided the impetus for the Japanese to get serious about paratroop weapons. In that battle, the airborne troops were equipped with standard rifles that were dropped in separate canisters and ended up landing in swamps some distance from the men, who then had to fight with just pistols, bayonets and grenades. The exploits of this intrepid, if unlucky, unit were immortalized in a dramatic painting by Goro Tsuruta (1890-1969; Tsuruta is the surname). For more on Mr. Tsuruta, see Goro Tsuruta | IFPDA). This image appeared in a magazine and also on postcards. Here is the postcard version. The caption on the left says 'Paratroopers landing in Palembang. Army sent to Sumatra region. Goro Tsuruta. With the permission of the Ministry of the Army.' The back says 'Issued by the Army Museum Association'.

Now I know you are dying to see how the gun comes apart, so here is a teaser: right and left shots of the gun in two pieces. In the first one you will note a screw with a D-ring through it at the front of the bottom (rear) half. Turning that is what loosens the wedge so the gun can come apart. But more on that later...

Let's start our detailed tour with the markings. Here is the top of the receiver. As noted above, the Imperial chrysanthemum, usually shortened by collectors to the 'mum', has been ground off, but you can still see some around the edges. The grinding of the mums was reportedly done to spare the Emperor the embarrassment of having his symbol fall into enemy hands (actually the Japanese always either cancelled the mum or ground it off on weapons that were withdrawn from active service in the Imperial Army or Imperial Navy, even when they were sent to allies or to other departments of the Japanese government). Below that are two kanji characters, ni-shiki, or 'Type 2'. The hole below that is a vent hole for gases to escape in the event of a case rupture. All Japanese rifles had this feature. The earlier Type 38s had two holes; when the Type 99 was introduced, they decided one would do (the Type 2 is a derivative of the Type 99).

The serial number, 16776, is on the left side of the receiver. Since total production was a little over 22,000, this one was made about 3./4 of the way through the production run. The mark after the number is the Nagoya Arsenal logo. Nagoya was the only arsenal to make these rifles. The small square in the upper right of the photo is actually a partially struck kanji character na (as in Nagoya), which was used by Nagoya Arsenal as an inspection mark.

The two halves and the barrel are also marked on the left side with an assembly number, in this case 775. This number bears no relation to the serial number; it is only a coincidence that it is so close in this case.

OK, so how do you get it apart, and what holds it together? At the far right of this photo you can see a round knob with a D-ring through it. That is the knob that you have to undo to take it apart. A couple of turns counterclockwise will do it. Then the wedge that holds the two halves together slides out to the right. If it is stuck and WD-40 or something similar won't loosen it, then you may have to undertake drastic measures. This one was completely jammed when I got it, but I think I did more than necessary to get it apart. I removed the sheet metal protective guard and the D-ring and then wrapped the knob in cloth and used a pair of pliers to get enough torque on it to turn it. I probably could have just removed the D-ring and left the protective sheet metal guard in place. Live and learn.

Here is the connecting part of the front half. Note the indexing hole to the right of the photo (it's below the barrel when the gun is oriented normally instead of being on its side). There is a peg on the front part of the rear half that fits in that hole to line things up. Now, take a look at the bottom of the barrel. See that notch? That's what the wedge fits into to hold the two halves together. The next photo shows it from a better angle.

In this photo taken from the right side you can see the notch very clearly. In the photo it is just below the flat metal surface that has that indexing hole in it.

Here is the wedge in the 'out' position. You can also see the sheet metal guard that surrounds this whole area and is held on by a screw that you see just above and to the right of the wedge. At the extreme right of the photo you can also see part of the peg that fits into that indexing hole on the front half.

This photo shows the groove in which the wedge travels. You can also see the indexing peg at the bottom.

Here the peg is half-way across the groove in which it travels. That indexing peg is again at the bottom of the photo.

Now let's take a tour from the muzzle to the butt of the rifle. You can see here that the front sight is protected by metal ears. The tip of the cleaning rod is also visiible, and at the very bottom, the stud for fixing the bayonet.

Here's a close-up of the ears and the front sight.

On the bottom you can see that the bayonet stud is marked with the last three digits of the rifle's serial number, 776. That little square button at the far left is the cleaning rod release.

Here;s the cleaning rod, which is 541 mm (21-5/16') long.

Here's the interesting part that sticks out the front w
