Thank you for the kind comment reinhard. I really did not expect any final judgment from the pictures, as you say, they might not be enough but for the most knowledgeable eyes to make an educated guess. My main intention was to show the piece to a group of people capable of enjoying them, I really appreciate all the comments, and there is something to be learned from most of them.
I will be more than happy to share my findings, regardless of the results it is a special piece. In spite of my rudimentary knowledge and exposure to nihonto, I was a member of the Florida token Kai, have been to several shows both in Orlando and Tampa, and have been an enthusiast and somewhat of a collector of nihonto for almost 20 years. I have seen a few exceptionally good looking blades, and this is one of them.
So, regardless of its provenance and pedigree, I recognize it as a quality piece and I'm very proud of it, definetly the best blade I have ever owned or will ever own. Regardless of the outcome, the discovery process is a lot of fun, and getting opinions from everyone is part of that.
