This one is a bit of a mystery. The mei reads Jugyoku, and it appears to be one of the later mei, but I can't find out much about the carver. There were two carvers who signed Jugyoku who are well known, and at least one and possibly three more who signed the same way all working from the mid to the late 19th century. Anyway, this is kind of a sweet carving ( perhaps a sweet oni is an oxymoron ). About 39mm by 34mm by 26mm, light wear and light patina...
