See attached images.
One is of the certificate - which I now know is only a registration document and bears no relation to authenticity.
The second image show the nakago signature on the left from a wakizashi I recently purchased. The two images on the right I found on the internet and would appear to be authentic 1st generation Kinmichi signatures. The two on the right are different blades but signatures somewhat similar. The signature on the left is obviously very different in style and would suggest strongly that it is a different person that engraved/etched it into the tang.
