@mecox What is the diagram at the bottom of the page about?  Something to do with seppa?

@KiipuThomas, the pics and discussion are largely about shin gunto koshirae and the number of seppa, e.g. 3 or 4 pairs as opposed to 2 pairs.  The 4 pairs look to be described as the classic for old tachi, and the 3 pairs on expensive gunto koshirae.  

The pic of newspaper at end shows article in "Rikugun Shikan Gakko" military school paper of Showa 19 (1944) that is basically saying the more seppa on luxury koshirae are not practical.

 

This last item is a very "flowery" discussion of the topic.... "Joto" (expensive) fittings of 6 seppa...when new  around the tsuba fitting not too tight or too loose (fitted with looseness of a fine hair) and this is usually for 2 pieces, but with 6 pieces it will become loose ("gata gata"). Also compared with 2 pieces the 6 pieces are out of balance.
