T434.  Iron tsuba, very slightly sukashi.  7.6 x 8.6 x .4 cm at the raised rim (the plate is .25 cm thick).  The nakago hitsu-ana is.8 x 2.8 cm.  Without the sukashi hole this is a simple mokko-gata plate tsuba with some carving.  The hole, however, is the eye of a plover (bird) with its wings and tail spread, making this into a design that is most often see on much smaller tsuba.  The rim is nicely raised and there are a couple very prominent tekkotsu above the eye on the rim.  The plate is carved: clouds, tortoise shell, and pines on one side and clouds and a stream on the other.  I like this one; think you will also.  Condition is excellent.  $225.
