Senmin (先珉), whose real name was Unno Shosaku is most likely to be Senmin (先民), listed in the Kinko jiten, as being a pupil of Unno Shomin (1844-1915) from 1894 to 1902. (l). Although Keishu Itsuto is not recorded in the dictionary, it is highly probable that this was another name for the artist given the identical workmanship of the second vase.
