Here is Chris Wauchop's 1/72 scale Einheits Diesel radio truck
Chris reports that this model was not easy to build.
Chris's Horch was painted overall Tamiya German Grey using the
Testor Aztek airbrush.
Pastel chalk was applied to depict dust, and additional shading
was achieved by spraying a thinned mix of Flat Black and Red Brown
followed by a selective oil wash.
The model was sealed with a coat of flat clear, which toned down
the weathering in general and the chalk in particular. More pastel
chalk was added after the flat coat to compensate.
