Nambu Type 14 Pistol

[sheepherder]

I was looking through Wilson's 'Textbook Of Automatic Pistols' last night and noticed this interesting picture...The book was published in 1943 and contains a publishers preface apologizing that the war in Europe interrupted the completion of the author's work. The pistols studied are from the 1884 - 1935 period. That makes this Nambu quite interesting...

It has the general grip shape of the Type 94 but resembles a Type 14, but an early one...Of note is the rear sight...I'm wondering if the flat grip section and adjustable rear sight indicate a shoulder stock???
