The rack is a Paul Cadovious 'Royal System' wall unit. This is still made though the modern copy isn't compatible with the original.
If anyone desperately wants this wall unit I have one in my garage, it's original, and I've owned it for about 40 yrs and it wasn't new then. It's been used in kids bedrooms, in the garage and some bits are missing but if anyone fancies a furniture restoration project, the underlying structure is well made and still sound. Cosmetically most of it is sh*t. I have a full depth three drawer unit, full depth desk, full depth drinks cabinet. A half depth unit with sliding wooden drawers, and a selection of full and half depth shelves. I really need to put it on eBay!
