Vintage shelving system Norway teak modular 1950's

Two units of three and four 74 x 30 cm teak shelves, adjustable in height on hanging brackets, with geometrically patterned openings. The shelves hang from the three wall-mounted brackets (3 cm wide, 1.5 cm deep and 160 cm high) which have an assembly of ladders with brass rungs welded to two black steel cleats. The welding work is exceptional. The wood has been sanded and varnished and the brass polished.
