This item was found in my parents' home. It is a set of two fittings, a fuchi and kashira, in the Higo style. The kashira is not hollowed out and has a thick, heavy feel. I don't know what era it's from. There is a light green patina, so I suspect the material is brass. There are wear marks in the nakago-ana of the fuchi (see photo 2), so I believe it was actually used. Please refer to the photos for the dimensions.
