Hi all,   Following on my from post regarding signature identification (thanks Ray, et al), I mentioned a very "rubbed / worn" tsuba on a Wakizashi which I came across whilst looking at a Jian. Clearly the Tsuba is not in the best condition, but I was interested in your thoughts. Does it have genuine age and if so, any guesses, or is the Tsuba more recent and has simply had a poor life?   I can post a few additional pictures of the blade if it will help the identification pro
