Moon's Bugei Dragonfly
That sword is very well known here in states among collectors and sword practitioners.
Moon is highly respected among many in the U.S. for his knowledge of the sword and his engaging personality.
darkness, you are very lucky to own this sword not only because it is a great sword but also because of it's previous owner, which probably doubles the sword's worth for being even more unique.
I was actually quite sad when I had seen moon had let this sword go, as probably James Williams will be, if he should find out also.
So enjoy it, as it is unique and one of it's kind!
