We have talked up and recommended the Ladderax modular shelving system on this site before, which looks rather similar to this particular design – 1960s teak Avalon wall and storage unit.
Both share the same purpose, being modular storage systems. It all depends on the 'look' you prefer and the layout you need. This set offers a bureau unit, a cabinet unit, two shelves, a glass door unit, three uprights and 10 supporting bars. If you want more, you just dig around for more, with the system able to grow and adapt as you need it.
All parts are in 'great vintage condition' with 'minor marks/scratches' you would expect from age. Lots of photos if you want to check that out in detail, with a price of £249.99.
