TARCISIO COLZANI for PORADA "DOMINO", Pair of Swivel Shelves, 1980s

Pair of shelves or bookcases by Tarcisio Colzani, Porada edition (Italy) in the 1980s.
Axes in anthracite black lacquered metal, shelves in textured blackened oak.
Each of the 4 shelves is modular and adjustable in height on its axis, it is also possible to place only 2 shelves on one and 6 on the other, or 3 and 5...
The distance of the central axis from the wall means that each shelf can be rotated through 180°.
The main axis is placed on the floor on a pedestal (see last picture) and is fixed to the wall with a metal "U" shaped structure, after having slid the shelves in and out.
The height of the shelves can be easily adjusted with a flat screwdriver.
Publisher's mark on the bases (see last photo).
Quality model still produced by the manufacturer but no longer in this texture, very expensive...
