Iron Tsuba Signed "Toshimasa" with Kao - NBTHK Hozon Tosogu - Dragon
Iron tsuba signed "Toshimasa" with Kao, with NBTHK Hozon Tosogu. This tsuba is decorated with a carved dragon around the edge. Unfortunately at this point I do not know which Toshimasa made this tsuba.
There was a lot of gold nunome zogan on the dragon, however now most is gone.
