This image is to be found in several places on the web and in books:

ISBN: 0415061377 Greek and Roman Technology: A Sourcebook by John W Humphrey p. 316 Section 8.30 Fig. 17 Design for a Vitruvian Water-Screw. Note that on page xiii permissions are recorded for several copyrighted images but not for this one.

The image appears with no source cited at http://www.math.nyu.edu/~crorres/Archimedes/Screw/VitScrew.gif http://www.math.nyu.edu/~crorres/Archimedes/Screw/SourcesScrew.html#vitruvius captioned "Construction of the water screw"

It also appears at http://www.redstoneprojects.com/trebuchetstore/archimidesescrewcutaway.gif http://www.redstoneprojects.com/trebuchetstore/archimedesscrew.html beside the Morgan translation of the Vitruvius passage.

Those two .gif images are not identical, but overlay perfectly when aligned. They differ in the way the transparent pixels were selected. This suggests they were not independently scanned.

The actual ancient latin text states that there is an illustration at the end of the manuscript.
