I am interested in purchasing tsuba made by the first three generations of the Bushu Ito school:
Matatsune. Called Ko-Masatsune (i.e. early Masatsune). He is listed as the ancenstor of the school and died in Kyoho 9 (1724).
Masanaga, 1st generation.
Masatsune, 2nd generation. He is called Go-Masatsune (i.e. later Masatsune), to destinguish him from the above.
Please let me know if you have any for sale or know someone who has.
