Last evening I e-mailed Miniart about a detail error on the suspension in the CAD rendering.
The CAD shows the mid production VVSS suspension spring arms instead of the more solid Early production VVSS suspension spring arms.
I also mentioned alternative roadwheels for the mid production M3 Lee.

Long story short, I got today a reply from Miniart.
They wil include 2 types of bogies and 2 types of roadwheels in this kit.

I am very, very happy!
