Vintage freestanding bookshelf in solid oak

Hello, here is a solid oak bookshelf from the 1970s. It consists of 6 shelves and 2 uprights. The whole is in very good condition with some signs of use. Very sturdy. The shelves are adjustable in height. It is made up of two elements positioned one on top of the other (though they can also be placed side by side). It can also serve as a divider as it has finishes on both sides. A small shelf is also available.
