Wall shelf unit - Elm - Elm and burr bookcase

This elm root wood bookcase was probably made by Willy Rizzo in the 20th century. However, it has neither a label nor a mark.
It is in a condition that allows use, but it requires restoration, as shown in the detailed photos.

It is composed of 3 elements connected to each other, so it is a single block that cannot be separated.
There is also a back panel, which we did not use.
At the bottom there are 3 small cabinets with a central shelf; the central cabinet also has 2 drawers. The left and right cabinets originally had a plastic tray (dark transparent plastic), which we did not insert, but which is present and intact.
The doors are fitted with metal hinges and the lower rails are also metal; one rail has detached completely, while the other is loose.
