The CMP chassis winch is driven by a ring and pinion. Unlike a worm gear winch, these are not self locking and would pay out cable freely without a brake. I would be extremely surprised if someone sould tell me there were CMP winches installed without a brake.
It might be that when your cab had its rebuild, the floor from a GS (without winch although some GS did have a winch) might have been used. This fits with the data plate shown at the beginning showing as a GS but is only a guess on my part.
