I just finished the three 1945-era Iwo Jima DVD's by Clint Eastwood back in 2006 and it seemed that only the Type 94 is depicted. IMDB notes that much attention was given to historical accuracy. I looked in the NRA Guide and if correct, it states the Type 14 was adopted in 1925 and the Type 94 in 1934. POTW confirms this.
This seems backward to me. The Type 14 looks more advanced, mechanically.
Anyone with any knowledge of this???
