Many years ago, I saw a revolving bookcase that intrigued me. I forgot about it but remembered it recently. After a little bit of googling, I think it was a "Tabard Inn Library Revolving Bookcase". Has anyone ever seen any construction drawings for these or for something similar?

This is an example.

Thanks in advance.
