B600.  Uchigatana Koshirae by Tokyo national Museum.  1985.  Softbound, 7 1/4 x 10″, about 50 pages in Japanese with an introduction and list of plates in English.  This is an earlier publication than the large silkbound book from Tokyo National.  Same idea, though: great koshirae throughout sword history.  Comes with 6 unbound pages of sword photos.

Corners and edges have been bent a bit; otherwise condition is fine.  11 ounces.  Was $45, now $20.
