A puzzle made in the former Soviet Union. Even in that region a very rare item.
The puzzle was produced in the former Soviet Union in the 1980's. OLIDJuS is a artifically constructed name: OLI is the short name for logical toy and D, Ju and S are the first letters of the inventors Dimitriew, Jurin and Stulnikow.
The puzzle is related to the Square-1 (or better: the Dodecagonal prism which does not behave bandaged and is usually made from a Square-1): There are two central pieces which allow a 180°-move and 18 segments in each of the two layers parallel to the central pair of pieces. These 18 segments make it into an octadecagonal prism.
The puzzle has a diameter (equal to its height) of 60mm.
Weight: 90 grams.
It shall be mentioned that the number of these puzzle increased by one in 2004 when Anthony Greenhill made a perfect copy of it and "perfect" is no exaggeration given the level of detail Anthonys sample copied the original. He used a modern Square-1 for the mechanism.
The year given here is an upper bound. This puzzle was shown in "The book of ingenious an diabolical puzzles" from 1994.
