   Some problems we have found with the selected faces in the stellation
                      diagrams presented in: 
           'Polyhedron Models' by Magnus J. Wenninger
           first edition CUP 1971.  ISBN 521 09859 9

Model 39: Fourteenth stellation of the icosahedron: the shown front faces
are not the rotationally symmetric. The two top ones are correct and the
bottom one should be extended.

Model 55: Ninth stellation of the icosidodecahedron: the faces in the
dodecahedral diagram should have dark shading.

Model 56: Tenth stellation of the icosidodecahedron: the faces in the
dodecahedral diagram should have dark shading.

Model 63: Sixteenth stellation of the icosidodecahedron: the six obtuse
angled triangular faces in the icosahedral diagram should have dark shading;
the other six are not part of the model.

Model 86: Small rhombihexahedron: the light and dark grey areas in the
hexahedral diagram should have their shades interchanged.

Model 88: Great icosicosidodecahedron: in the hexagonal icosahedral diagram
the small triangular areas in the interior should be light grey, not dark
grey.

Model 90: Small dodecicosahedron: the dodecahedral diagram should have the
shades interchanged. Also the (currently) light grey large trapezoidal areas
penetrate too far towards the middle; they should be cut off on the same
line as the adjoining (currently) dark grey triangles.

Model 93: Quasitruncated cuboctahedron: all the faces except the central
triangle in the octahedral triangle should be dark grey.

Model 96: Rhombicosahedron: the icosahedral diagram  should have the shades
interchanged.

Model 97: Quasitruncated small stellated dodecahedron: the central pentagon
inside the 10-pointed star should be light grey.

Model 98: Quasitruncated dodecahedron: the small quadrilaterals round the
edge of the decagon should change from light to dark grey.

Model 108 Great quasitruncated icosidodecahedron: in the rhombitriacontal
diagram the two triangles at the right edge should be shaded like the two at
the left edge.

Model 116 Apart from the very small areas that Wenninger admits to not
showing, there is a sizeable triangle on the left edge of the snub diagram
just below the top (back) area on this edge which is also a back face.

Model 118 all the faces along the left edge of the snub diagram are back
facing.

Model 119 The pair of corner faces at the top right of the hemi-hexeconta
diagram should be swapped front-to-back thus making the diagram reflection
symmetric about the almost horizontal axis.

                   *************************

     The comments above are real problems with the stellation diagrams shown
in the book. Additionally there are 2 polyhedra which are difficult to get
right:

 Models 38 and 39 have vertices in the middles of some of the straight sides
of the faces. These models must have their faces selected with 'Points'
(rather than 'Lines').
 In model 38 there are vertices in the middle of the base of the Front 'V'
and in the long side of the bigger Back triangle.
 In model 39 there is a vertex on the middling sized edge of the Back
triangle as Wenninger indicates with his split tab in the cut-out diagram.
