Description
This instrument sits in a rosewood box with rosewood cross piece. Fifteen parallel bamboo rods pass through the cross piece. Each rod has two wooden beads above and five below the cross piece. The beads are rounded, like those on other Chinese abaci. Brass corner pieces hold the box together.

He lent the object as an example of a modern Chinese abacus. He donated it in 1960.There is no mark by a maker.
