The gun was the first on the bench and it was a very fast build (in total 8 hours - very fast for my standards 

)
I decided to use the color modulation again and the gun looks like this
This was immediately after application of base color, shading and highlights.

The chipping and "aging" are not complete (looking at the pics I found a few places that need retouching) and it's now "corrected".
The tractor is half built and I guess that I'll start painting it by the end of the week.
Currently on the bench
