B877.  Kokuho Token Zufu  By Homma Junji.  1936.  Loose plates in 16 folders inside a cloth bound, bone or ivory clipped folding case, 12 1/4 x 15 1/2 x 5″, in Japanese.  This is a very important and difficult to find reference.  164 heavy paper plates with the swords that were ranked Kokuho (National Treasure) before WWII.  Between the plates is a sheet of lighter weight paper with descriptions, history I bet, and other information.  Almost all the plates are crisp photos (remarkably crisp for the time) but there are a few oshigata.
