Today I was able to review a Shin Gunto in person to verify its authenticity.
There are markings on the Nagako which I posted in the translation help section but also added attached. The blade seems machine made, has some small nicks and damages but nothing major
There is also a small marking on the Habaki and the same on the Fuchi.
What is your impression on this looking at the attached pictures.
I truly appreciate your help in this and thank you upfront for any info you may have
With best regards
