While I continue to clean up and mildly preserve the sword I presented in the traditionally-made ninhnto section, can anyone help me identify this Tsuba that came with my in laws sword? It too was stored away in garages for over 70 years, having come home with my wife's grandfather from the Tokyo area where he was stationed just after World War 2 (Navy shore detachment). For those who did not see the other "Help Needed with In Laws' Sword thread", the sword came with only the blade, the Tsuba, and two spacers (seppa). The other fittings were not present and the whole thing was held together with a piece of large, twisted, copper wire. In any case, can anyone help identify the Tsuba. It is 3.5 inches in diameter.
