Mary Morgan and I have written a paper on the Phillips Machine: 
 
The Secrets Hidden by Two-Dimensionality: The Economy as a Hydraulic Machine. In:
Displaying the Third Dimension: Models in the Sciences, Technology, and Medicine, eds. S.
de Chadarevian and N. Hopwood, Stanford University Press,
forthcoming. 
 
The paper provides some charts and pictures of the Machine and references to archives from
which we could select them.
 
Best wishes, 
Marcel Boumans
