Sd.Kfz 7/1 with 2cm Flakvierling 38 (early)

I have begun work on the wheels for the Flakwagen. I am using Fruil tracks on this build. This is the first time I will be using white metal tracks. I wanted to show a picture of the difference between the Fruil drive wheel versus the Trumpeter kit part. The Fruil track wheel is accurate but I am not sure  how trumpeter came up with their version of the wheel. It's totally inaccurate. The Fruil wheel also has the tread pattern on the hub which is quite nice.
