I am not a student of Japanese weapons but I have never seen the Type 14 listed in any reference book as the Taisho Type 14. The only Japanese weapon I recalled listed as a Taisho is the type 3 Machine gun IIRC. Usually I see it listed this way "The type 14 pistol was designed by Japanese general Kijiro Nambu circa 1925 (14th year of the Taisho emperor, hence the official designation), as an iprovement over the earlier pistol of his design. This pistol was adopted by Imperial Japanese Army and widely used during all S-E Asia campaigns and through the World War 2 as a standard Army sidearm." Under the listing as the Nambu Type 14 Pistol. However, I will bow to someone who has more knowledge than I do about these weapons. I thank you for the information.
