My friend’s late father brought this Late 1944 Shin-Gunto back from WWII. It came from the Hiroshima area (outside the destruction, obviously). The blade and mounts show their age and lack of proper care, but are not terrible. Yes, I am educating her on proper care.
Please check my interpretation of the tang markings.
The date side looks to me to be: 1944, August; lucky day.
On the mei side there is the Star arsenal mark and what looks to me to be: Okishiba (Okishiga?) Yoshisada, then kin, tsukuru, kore (humbly made this?). This is the first Shin-gunto mei I have tried to decipher, let me down gently…
There is an Okishiba Yoshisada in the list of the Rikugun Jumei Tosho. Does this blade seem consistent with his work?
