Absolutely incredibly put together thread and invaluable to documenting and suggesting Japanese small arms.
I truly do and sincerely thank you DELAVR Killerwolf1024 Slakrrrrrr NonNational skultew1234 VINICIUS LAG@live for every bit of collaborative contribution in this. Along with everyone else who’s put in so much incredible work researching and suggesting items for Japan. 
Wow supernice!
@_DELAVR When you have time you can check this two I dismissed one as fake cuz I have no idea what it is but the other one looks legit:
This is Drum-Fed LMG for Chinese Warlords: the Finnish LS-26/31 Only about 1,200 were shipped before the Japanese government persuaded the Finnish government to cut off exports, as Japan was fighting in China at the time. So its possible that some of those where used by Japan. It has 75-round drum.
And the other one is provided as a east Dutch gun modified by Japan however there is no info about it so I just dismissed it since it doesn’t resemble world war 2 gun :
The second one feels really fake but the Chinese one is very real.
There were no LS 26/31 machine guns in China; in Finland itself, only 50 units were produced with the 75-round drum magazine (which was incompatible with standard models). It is almost certain that China ordered versions of the LS 26 chambered for the 7.92 Mauser cartridge.
It seems pretty obvious to me that this is an AI-generated image. For starters, the rear and front sights are at different heights, making it impossible to aim the weapon. The magazine is very strange and is located directly under the barrel rather than where the bolt should be. The receiver looks like it’s made of aluminum, which was hardly ever used in WWII small arms. There is a barrel visible on the outside, yet it’s missing inside the cooling shroud. And so on…
That exactly what I trough xD I love how he made the magazine it looks so unique xD
so only 50 units where produced with 75 mag sad I thought its more.
On this website I have found an interesting Type 100 Tsing Tao Hybrid SMG:
Do you know something about it ?
I’ve always wondered something (and excuse me if I didn’t see it already written there) could the Type Hei semi-auto and the Type Hei automatic rifle have used the same magazines, like the ZH-29 and the ZB26?
Unfortunately not due to the curvature of the magazines relative to the magwell in regards to both rifles as far as we’re aware.
That’s quite unfortunate, to be honest. Otherwise, we would have had a very interesting option for a Japanese semi-automatic. The Hino Komuro is quite interesting to use, so a similar one but with twice of rounds would have been good
respectfully, I think that is just a prop used for movies.
There is no magazine release mechanism and the bayonet lug is an illogical location.
Thats not a real Type 100 magazine either and I doubt someone would have designed a new magazine for a one of a kind gun.
Well, you say that, but actually the Early and Late guns don’t have interchangeable magazines. 
You kinda missed the point here.
Both late and early Type 100 were mass produced, while this is the only known gun of its kind.
Yeah but it has early variant release mechanism it looks like some partisan gun made of scraps of SMGs. It has all the features of Type 100 early combined with SIG 1920 or Tsingtao Type 16 submachine gun it could be some prop also its possible I have no info on it just saw it on forgotten weapons. But its made of Type 100 early for sure. The release mechanism the bipod all this is feature of the early type.
Very similar design.
I have been hunting for odd Chinese weapons for sometime now and I came across hybrids like SIG1920 and MP28 (no rear sight either to make it even spicier).
But if this gun was real, it must been made by the Chinese and use 7.62 Mauser so it would have a straight magazine, which it does not.
Well probably but it can be after war PPSh mag that will be strange with early design type 100 or there is curved 7.62 Mauser mags or it can be not original mag something that they just put on display.
Do you know if there were prototypes of the Type 100 in calibers other than the 8mm Nambu?
Nambu Type 1 SMG was produced by China during Chinese civil war in .45 ACP so I wont be surprised if another early concept Japanese SMG was copied by China.
Now that you mention it, wasn’t there a rather crude copy of the Type 2 as well?
Well yes the Chinese copied a lot of stuff xD
