I just bought a tsuba that looks just like one listed in a book that they shared with the ad.   I am including a photo of the tsuba as well as two photos of the book shown in the listing that has a tsuba attributed to Hayashi Matashichi.  Sadly, they didn't  mention the book name in the listing. The tsuba I bought has NBTHK H papers to Higo.  Do any of you by any chance recognize the book that is pictured?  I can't read the page number but it looks to be 1XX.
