T302.  Sukashi tsuba in brass, signed Kofu Ju Toshimasa.  6.3 x 7.1 x .4 cm.  The nakago hitsu-ana is .8 x 2.7 cm.  A rain dragon is the subject.  Bob Haynes has a smith signing Kofu Ju Toshimasa working in the 17th century; this may be him?  This design worked in brass is often seen but I think this piece is a step above most.  The brass is lustrous and condition is excellent.  $225.
