British army trucks of the 30s. Identification

[Konstantin Chernov]

The pictures probably show some maneuvers or training.
1. Thornycroft A3/FB4. Behind them is an Austin 7 passenger car.
2,3. I identify this truck as Guy BAX.
4. The first one on the right is Guy BAX, the third one is Morris Commercial type D. And what is the car between them? In the front, in the center of the frame, there is some kind of massive bracket supporting a spring or wishbones (it is hard to see). It was not possible to find the truck by this design feature.
5. Guy BAX
