I have this Kozuka signed Masa Haru which is similar to the Kozuka presented in "the Arts of the Japanese Sword" of B.W. Robinson plate 81. It is mentioned that it is from Mito school. There are so many Masa Haru artists with the same Kanji....Would it be the Soiken Masaharu Haynes H03925.0?
Does some one have tosogu pictures of this artist?
