Thanks everyone for the information starting to get a little, overwhelmed the more a dig and dig into what everyone saying. Just going to repost some photos to see if someone can give me clarity on what the individual markings mean. Love the enthusiasm of this group, and find myself digging deeper and deeper on the net to find information could become a little obsessive.
there are no other markings on the other side of the nakago, or in the blade itself
But I am, Shore and number of you would understand.
