C260.  Iron tsuba with brass inlay.  7.3 x 7.5 x .35 cm on the plate.  The nakago hitsu-ana is.8 x 2.4 cm.  I don’t recall seeing nautilus as a design on tsuba before; wonder why.  This is probably Heianjo Zogan or Yoshiro School.  One line of brass on a shell and one rectangular dot of ten zogan are missing; otherwise condition is excellent.  $225.
