T252.  Tachikaneguchi tsuba in gold plated yamagane (believe I have that right).  8.1 x 8.2 x .5 cm at the raised rim (3 mm plate).  The nakago hitsu-ana is .8 x 2.6 cm.  A former owner has given this to mid to late Edo Kinko; works for me.  The gold has been worn away except for in protected areas, which combined with the natural patination of the yamagane gives this tsuba a nice, organic appearance.  Condition is excellent.  Was $190, now $150.
