Shakudo fuchikashira decorated with gilded crane, rock and flowing stream. I know of two examples of very similar fuchikashira, both signed "Otsuryuken Kaneyuki". Pictures of both are placed under photos of this set.
This one is unsigned however based on similarities It is safe to say that it was made by Hamano School.
There is some inlay and patina missing.
Size:
Fuchi: 38 mm x 21 mm x 10 mm
Kashira: 34 mm x 18 mm x 9 mm
