This one was much harder then the finished product show for it's self. This is more or less really 2 models in 1. The 37mm anti tank gun was part of a stand alone 37mm gun that can be used to convert a 251 into a 251/10. So the whole AT gun had to be built *which was tons of tiny pieces* then the 251 half track, which to get the wheels to move and pivot was very hard. I still froze 1 up though :/ I was able to find some flat paint finally so this is my first model that isnt super shiny. It has a tad of black wash to show depth.
