Italian Modular Rosewood Bookcase Wall Unit by Osvaldo Borsani for Tecno

Large modular rosewood bookcase/wall unit by Osvaldo Borsani for Tecno (ca. 1960, Italy).
Composed of six gold aluminum uprights forming five bays/sections.
Includes:
-locking bar unit with a removable (non-adjustable) shelf and glass surface
-three-drawer chest, a locking cabinet with single adjustable/removable shelf
-twelve shelves
-all original brackets/mounting hardware and two keys.
The set can also be divided to create two separate units (1 and 3 sections or 2 and 2 sections).
Alternatively, we have a second six rail/five section unit, and the two can be combined to create a grand eleven bay system.
Gold aluminum rails and black steel brackets/hardware are all original; rosewood has been refinished and is in very good condition with only light, age-commensurate wear.
Note that the aluminum rails are included (the black backings are ledger boards that we mounted in order to work with the conduit we have running along our wall – they are not necessary for standard wall-mounting and will not be included).
Decorative objects/seating are for illustration purposes only.
