Field flattener, Williams old one.

Does anyone have a William Optics 102GT with an old style flattener/reducer, and can post an image or two showing their setup so I can see how it all fits together.
This is the first time of trying to use the flattener, not needing it on solar stuff...
Back focus diagrams are all well and good, but often don't include the telescope and where the focus tube is....
