The Type 19 cavalry officer sword is the cavalry cousin to the "Meiji era kyu gunto family" officer swords. As such, there is a combat version with a real blade and assembled by mekugi, and a dress version with a chromium plated blade assembled by bolt. The fact is that, due to the small number of cavalry régiments during the Meiji era, this sword is very rare, although the dress version appears slightly more common than the combat version. It is rarer than the Navy kyu gunto.
According to Fuller and Gregory, the dress version appeared a bit later than the combat version.
I should also be mentioned that some cavalry officers, among whom General Akiyama, favoured dress swords or the arsenal-produced type 32 NCO cavalry sword over the traditionally made but more delicate Type 19 cavalry officer sword. The Type 32 sword was very robust and popular for this reason: it was produced from 1899 to 1945. Therefore, there were only a few cavalry officers to start with, and some of them did not use the sword prescribed for their rank, which makes the said sword even rarer.
I like this sword because it is harmonious: the Army and Navy kyu gunto have pommels without floral motif. On the cavalry sword, the pommel is rounded and flows from the back strap: the floral motif is uninterrupted and curves around the pommel, which is very nice.
Although the Navy kyu gunto, with its remarkable scabbard and precious mountings, is the most beautiful Meiji era sword, the Type 19 cavalry officer sword is very elegant.
