Hi,
Back home :D
Pictures are often better than long words, specially when english is not your native idioma.
Shigetaka shodai:
Shigetaka nidai:
Hope this can be helphul.
Hi,
The oshigata promised , you can see the differences and the lack of the kanji saku 作:
The Shigeyoshi quoted by Grey is not the same, he was mainly a tosogu maker. On his signature the kanji Ume is different 梅 for him and 埋 for yours.
Hi,
Umetada is the school name, Shigeyoshi is the swordmith artname. Shigeyoshi (real name Myoshin, common name HIkojiro) worked mainly from 1624 to 1643 and was mostly a metal worker. His swords are very few. I have only one oshigata from him and the signature of your blade does not match this one.
It is dark here now also i will post a picture of this oshigata to morrow.
Hi,
The whole signature is far to match a mei by Yoshimichi Shodai ( the first) or following. Is your blade bearing a kiku-mon (chrisanthemum flower)?
You can find an excellent example here
Hi,
I would add
Samurai, The weapons and spirit of the Japanese warrior by Clive Sinclaire
Cutting Edge, Japanese swords in the british museum by Victor Harris.
If you can read french.
Nippon-tô - Les sabres shinto - Les sabres Koto. Both by Serge Degore.
Hi,
Shodai Tadahiro, nidai Tadahiro, shodai Masahiro (daimei) and Masanobu (daimei) signed this way. Gimei may be more difficult to detect.
Imho i think it is gimei, two atari on the kanji Hiro do not match, one on the kanji Tada too.
Hi,
According my books nothing can be clearly established about Senjuin Yoshihiro even his work. the only thing we can be certain is the rarity of his works. Still according my books all blade with niji-mei should be from late Kamakura period, those with a naga-mei are made in Nanbokucho period. Imho the sugata of your blade does not match late kamakura ones.
Hi,
If i'm not wrong, the item 08727 is signed Musashi Daijo Fujiwara Tadahiro and is a blade from shodai Tadayoshi the other item 08112 signed Hizen koku Musashi Daijo Fujiwara Tadahiro is from shodai Tadayoshi too but clearly stated as gimei.
