Iron Tsuba Signed "Choshu Tomonobu" Decorated with Dragon
Iron tsuba signed "Choshu Tomonobu". Tomonobu was part of the Nakai Choshu School family. According to "Choshu Tsuba" published by Iwakuni Museum he was a second son of Tomotsune and and brother of Tomoyuki. He was adopted by Kawasaki family and become a Samurai.
Signature on this tsuba is very different from all other Tomonobu signatures I was able to find. However craftsmanship is rather similar to the one from example I placed at the end of photo section. I do not know If this tsuba was made by Tomonobu, however it would be rather strange to fake his signature.
