F121.  Thick iron plate tsuba signed Jumyo in gold.  7.2 x 7.5 x .55 cm.  The nakago hitsu-ana is .7 x 2.7 cm.  The kotsuka and kogai hitsu-ana are lined with gold also and the udenuki-ana are lined with silver.  I believe this to be the 1st tsuba I’ve ever seen with a gold signature; must be special.  $375.
