To all that can help,
I aquired this blade about 25 years ago, and know it was brought back from Japan by my Father in law 1n 1965.
It is Katana, approxamatly 31 cm., Shinogi zukuri style blade in a simple shirasaya with no Habaki. Ihori mune with a Hako (box) Harmon. The blade has some surface rust, and finger prints, but no visable pitting,ie: I believe it can be polished out.There are 5 Kenji on the blade, the top (from the tip down) is an obvious 3, the other 4 are very faint. Im thinking this possiably a Nengo.
The Nakago is 6 cm futsu shaped with a Kurijiri tip. It has 2 Kenji, I am presuming this is a Mei. Ironicaly, there is a blade in the 5k t0 7.5K for sale link in this site that has a similar kenji, Naoshige of Kii, if it helps.
I have included the Nakago Kenji, how ever the blade Kenji are very faint, I tried my best to photograph them but they are invisable as a collective photograph. If you E-mail me, I can send closeup pics of the blade Kenji if needed.
My main intent is to asertain if this blade is worth restoration and regiserting.
After looking at Dr. Stein's page, I can honestly tell the 80% of what your NOT supposed to do to a blade HAS been done, (not by me).
