I have been reading about the Ki-27, and learned that the later models included a 12.7mm machine gun in the nose which replaced one of the 7.7mm machine guns of the earlier models. I am currently looking for sources that can confirm this claim. From what I’ve been able to learn these models was called the Ki-27B. Would very much appreciate any good leads!

Can’t say I’m very knowledgeable about aircraft in general, but maybe @Grzegames would be able to assist?

Ki-27B or Ki-27 Otsu is a version with a different canopy and engine. I can’t find any reports of Ki-27 with a 12.7 mm machine gun. I don’t recall any book sources about it.
@skultew1234 maybe you know something more?

I’ve never heard about Ki-27 with Ho-103 and a little confused with it.
Fast checking books what I have (not really many about Ki-27 but anyway) and Japanese wiki + sites gave nothing about Ki-27 with Ho-103.

Thank you all for the replies @BSpiel8 @Grzegames @skultew1234 !! I don’t have any sources myself, I’ve just been seeing various websites and videos mentioning that the later models of the Ki-27 were upgraded with the 12.7mm alongside the addition of a canopy. I’ll post a few that I can recall.
I know these aren’t primary sources, which is why I wanted to track down more information. So I do appreciate the help in sharing what you know!
