vintage wooden Lotus-Flower brand abacus

Description

I got this at a local estate sale to use in photographic still lifes, and no longer need it.
I do not know the type of woods used; I believe the beads move along bamboo, but am not sure.
The approximate dimensions are 7" x 4 1/4" x 7/8" or 178mm x 109mm x 23 mm.
