This is 2 cheap kits tamiya's Horch 4x4 1a and Tamiya's 20mmFLAK38. This conversion is scratchbuilt and prob isn't all that accurate I do have a picture of one of these field conversions but it was set in North Africa and didn't show how the gun was mounted so i used "artistic license" for the conversion and set mine on the eastern front.
this kit was basicly built so I could try out several different modeling ideas. one of which was useing chalk washes to do something to make the basic panzer grey scheme less...boring and grey. the other thing was making realistic looking wood from plastic strip styreen and making a "muddy" vehicle.
the wash was water and black pastel with a drop of dish soap to help it along.
The mud was tamiya putty, polyscale acrylic "dirt" paint and finly gound dirt.



There are more images on my website at the following url.. several of them are good closeups of the weathering..
