For example, Type 38 was finalized in Meiji 38, 1905.

The official number of the crooked machine gun is Dazheng 1 1 machine gun.

Later, the numbering was unified, and they were all numbered according to the Japanese era.

For example, the Type 92 heavy machine gun was finalized in 2592, taking the last two, Type 92.

Since then, Type 99 rifles and Type 96 light machine guns have been named according to this rule.

As for the names such as crooked stick, pheasant neck, tortoise box and March 8 big cover, they were all later called according to the characteristics of these firearms.

For example, the handle of Taisho 1 1 light machine gun has a curved arc, which is vividly called a crooked stick.

There is a circle of heat sink on the barrel of Type 92 heavy machine gun, which looks like the hair in the neck of a pheasant.

After the Southern 14 pistol is loaded into the holster, only a small barrel is exposed, which, together with the round holster, looks like a tortoise, so it is called the tortoise box.

Type 38 rifle has a dust cover, so it is called 38 big cover.
