Help with smith “Minamoto Yoshiteru” Gendaito era.

[Jon]

Does anyone have any information on Minamoto Yoshiteru, he was an active smith in the Gendaito era.

[ROKUJURO]

Jon,

there is no "GENDAITO era. GENDAI-TO are swords made after 1876 so your smith may have worked in MEIJI or TAISHO eras or even later.

Sesko doesn't list one in that timeframe.  Not unusual, though.  There were over 400 smiths that worked just in the WWII era alone.
