Nothing at all. I guess i picked to rare of a gun. It's a Hake shiki. It was designed by Bunji Hamada after requests for a handgun that would use standard Japanese Army ammunition, but be easier and cheaper to produce than the Type 94 (and some say, also out of a desire for a better weapon than the Type 94). To this end, Hamada chambered a version of the Hamada shiki for 8mm Nambu and lengthened the barrel a little bit. Originally produced in the Toriimatsu factory in Tokyo, it was transfered in 1944 to Notobe.
Unfortunately, Hamada succeeded on nearly all counts, but the weapon actually proved to be more difficult to manufacture than the Type 94, that is; it plainly became too expensive for the strained empire at war (costing 164yen compared to Type-94 at a cost of 80yen). The Hake shiki, (also known as the Type 2 pistol) was only made in very small numbers, with about 1500 being completed and distributed, plus parts for another 4000 that that were surrendered to the Allied authorities after the end of World War 2. After the war HGL (Hamada Gun Laboratory) in Bunji started to focus on customizing hunting guns.
The 8mm is a cool looking round to. Looks like a 357 sig. here it is next to a .380
Hamada is still around today.
