H404.  Another Holbrook tsuba: “Ko Tosho, Muromachi, Udenuki Ana”.  8.3 x 8.7 x .4 cm at the raised rim.  The nakago hitsu-ana is .8 x 2.7 cm.  I’m a bit surprised Skip has called this Ko Tosho; a raised rim is usually associated with Katchushi.  Oh well, he knows more than I do.  This does not appear ever to have been mounted.  $175.
