WWII Japanese Samurai Sword SHIN GUNTO (1943 by Seki Showa Swordsmith Kiyomiya )
Here is one of my prized WW2 Japanese militaria possessions second only to my Arisaka type 99 with non-defaced Chrysanthemum and intact aircraft sights.

This sword has a blade length of 26.25 inches (66cm). I believe it was manufactured in in 1943 by Seki Showa Swordsmith Kiyomiya <—- (not 100% on that info)
