P104.  An iron sukashi tsuba.  7.2 x 7.3 x .35 cm.  The nakago hitsu-ana is .8 x 2.6 cm.  I have found another tsuba very similar to this one online and there the sukashi is described as Koro hanaike (incense burner and vase).  Better than any idea I can come up with.  Condition is excellent.  Was $200; marked down to $160.
