Dear All, I have been interested in the theme of rats in Japanese art for a while but sword fittings are not my forte, to say the least. A tsuba depicting a rat has just caught my attention but I would really like to hear your opinion before buying it. It is described as iron sukashi tsuba. Dimensions are 55,4x52x4,3mm. Is it genuine, and if so, would you be able to help me with the school and age? Regards, Lukasz
