J117.  Namban tsuba consigned to my site.  7.4 x 7.5 x .45 cm.  The nakago hitsu-ana is .7 x 2.7 cm (.9 cm at the middle).  This tsuba’s owner conjectures that it resembles a piece from monsoon Asia but the precise carving and nunome gilding suggests a Japanese made piece in the former style.  The unusual nakago hitsu-ana would have been made to accomodate differing tang systems.  The kotsuka hitsu-ana (on the left in my 1st picture) is a separate piece of metal set into the plate.  $345.
