Hi Mark S, I noticed yesterday that the example you put on was signed tachi mei. Now then, that was typical (but always an exception to the rule) of Tadakuni line katana. From what i understand, wakizashi where signed katana mei, but then again, maybe exceptions out there, not sure.
Anyway, the mei on your example is shoddy to say the least, especially "wara" . An attempt at "Harima no kami", the son of Shodai Tadakuni or possibly the Shodai in his later years (so ive read, gets confusing). The example in Jims link is that of the Shodai.
20 watchers, someone looking for a bargain Josaku smith maybe, wishful thinking.
