I found my copy of D. F. Horne's book, OPTICAL PRODUCTION TECHNOLOGY, Crane, Russak & Company, New York, 1972 which is aimed at the professional optician, with many machines illustrated.
The pentaprism moving across the mirror on a track, together with an autocollimating telescope, is described in the context of measuring radii of curvature, so it is only peripherally related to the topic of this thread.
However, in the section just preceding the spherometry discussion in Horne, he has an illustrated discussion of Fizeau equipment and techniques. The 45 cm aperture liquid reference Fizeau interferometer at the U. K. National Physical Laboratory at Teddington is shown in cross-section.
I bought the book from the estate of A.S. DeVany, author of Master Optical Techniques (Wiley?) My copy is in storage, so I cannot comment on what is in there about this thread topic.
I have a 5 inch Davidson Fizeau planinterferometer which I am not using, as well as a professionally made Newton's rings viewing box. I am in southern California.
