I found one walktrough that gives a wrong picture of the second wheel. The only right positions are found in the room you can visit through the linking book.
I took the 'blunt' approach of taking screenshots of all the displays in that room and pasting them into a wordprocessor to output them on my color printer. They were of tremendous help that way, though I only needed pictures of the 'three wheels', 'highlighted path at a mozaik floor', and 3 shots of '6 rotating numbered statues'.
