Thank you all for the very encouraging remarks. Bruce, you are correct, the note is the translation for the wooden tag. I have the fuchi and the peg and a screw, although the screw was not attached to anything and the retaining lever is broken. The tsuba is plain iron and also has a Nagoya stamp on it. All parts are there except for the tassel ring (?) which would have been on the Kashira, as far as I can tell.
The sword that calls to me is a war trophy brought home from Java by the father of family friends attributed to a smith named Nori Taka. For 25 years they have said "no" to selling it to me, but they have my number, so maybe some day.
