Sonderanhänger 116 German heavy duty trailer

In the last weeks I had a chance to finalize the painting for my first Sonderanhanger 116. 
So far I have now three versions. The one from Metal Troops, nice, but the one I bought, some years ago has a slightly damaged frame.
From Shapeways, I have the version in white strong and flexible (WSF) and with Frosted ultra detail (FUD).
Below are some pictures where you can see the difference. 

left the Metal Troops version, then WSF and right the FUD version
