It would be nice to know where Yamanaka? got this information. Here are the Kanji that were taken from Rich Steins site where the article states the names are referenced to the kanji tables on the site. I do think there might be some incorrect ones as typing errors etc.   Norinaga 則永, Even though I would think this might be Shikkake Norinaga (則長) and c. 85cm tachi 1x daitō, 1x shōtō Shimada 1x daitō Hiromitsu 広光, I'd think Sōshū Hiromitsu but there are other possibilities too 1x daitō, 1x
