Hi guys, I'm new member and i recently got 2 nbthk papers but cant identify swordsmith of one and koshirae maker of another. Please help. Katana which is said made by masakiyo in 1866 but cant find any info about swordsmith with that name making swords in that period and untranslated certificate for koshirae. I will also add photo of tsuba of masakiyo katana for identification and for evaluation if this is genuine piece or fake one.
