Sd.Kfz. 10/5 Flak 38: wrong data ?

[No_Face]

I had made a topic (in the wrong section) about a possible data error on this vehicle.

I take the opportunity to put it in the right section to add another possible error. The data of the vehicle indicates a maximum speed on road of 69.6 km/h but I can't exceed 53 km/h.
