Bookcase - unusual-looking shape (Waldridge Park DH2)

I bought this bookcase several years ago from a recycled-timber workshop. It’s a perfect size for paperback books, or a single ornament on each of the four shelves (5 if you count the base, 6 if you count the top).
The dimensions of this square but tall bookcase are about 20cm on each face. So a square that’s 180cm high.
The wood wasn’t stained so I painted the interior surfaces flat black then applied leftover wallpaper on the outside. This emphasises the twist effect.
In actual fact it is simply the shape of the sides that make it look twisted. I’ve displayed the books to make this effect stand out.
The unit is solid wood, with the shelves built in, so is quite heavy. It’s supplied with a bracket that screws to the top and the wall to keep it safe from toppling.
Would make a perfect project for someone.
I’d prefer collection only please as I wouldn’t know how to start packing it!
If you want more detailed photos let me know.
