Tchoty, or Russian Abacus

<< >>
Description
This modern Russian abacus has a black plastic frame and 13 parallel metal wires that hold beads. There are ten beads on each rod, with two blue ones in the middle and four white ones on either side. On the third and sixth row, the leftmost bead is also blue. The fourth row from the bottom has only four beads - two blue ones in the center and a white bead on either side.
The cardboard envelope is yellow, red, and tan, with a drawing of the abacus. The envelope is marked in pencil: MOSCOW (/) Sept. 1958 (/) G.U.M. Other marks on it are in Russian.
