To me it still looks like Kosei 2 = 1456, 8 Gatsu, = August.
As to the name, if my Japanese sword teacher says with confidence that it is Morishige, then that is good enough for me. He is on the board of the NBTHK in Tokyo and has an amazing eye and memory and dedication. I will however ask him for you, Heni, how he sees that name there!
You know Piers I wrote my thoughts without seeing your Morishige call. I think your guy is right, you can just see the 皿 peeking out. . Date I would consider as 永正 Eisho. There were two of the period and one that signed Bishu, Shinzaburo Morishige. John
Guys, I think this blade is signed Bishu Osafune Narishige 備 州 長 船 成 重. Hawley lists a couple of smiths using this name and dating to 1394 and 1467 but there were probably many more at different dates. Ian B
Hi all, there are several Koto Bizen Morishige from the Kunimori line (....I`m convinced that we had to read the kanji in question as "Mori"). Starting from around Ôei till Eishô. Nihonto Koza (Koto, Part 3, Page 320) mentioned one at Eishô. Unfortunately no example of his mei ore his work style. Heni, you can see remnants of kaeri at the kissaki, quite a lot of material has been lost....it`s a pity.....
Heni, it's your decision at the end of the day. However, I suspect you don't collect nihonto. This blade bears a fatal flaw. The pending offer you mentioned seems fair......especially the smith is not one of the "big guys". Please note, it's only my personal opinion!
I share the opinion of Uwe. If you can sell it, sell it without hesutation. It is already a chance to find someone who wants to buy a sword, with an important defect. Sorry for you but the absence of boshi is really serious.
