Do a Google search using keywords "wheeler wilson library cabinet" and you will find a couple of sites to obtain some information on these machines and the cabinets. I went to look at one of these about a year ago. The machine had a lot of rust on it and the "books" were in poor condition. The mirror would have needed to be re-silvered. The wood wasn't great either. I passed on it due to its poor condition but it is the only one that I have seen.
