Hi Roland,
Like you I have an interest in the Yoshii school, having purchased a tanto by Kiyonori a few years ago. The mei is Fujiwara Kiyonori, second generation Eikyo. It was purchased by a New Zealander in Japan in 1951 for the sum of 4000 yen from an "Authorised Sword Expert" M. Mishima, this is stamped in red on all the accompanying paperwork.
It is a text book example, small gunome with nie in the tani.
