Keith, I'm certain it's for winching, I distinctly recall seeing a diagram when we were kids, showing the use of scotches on a Cab 13 FAT. A chain (or cable) is attached to the scotch plate under the rear wheel and hooked onto the spring hanger, anchoring the vehicle for winching forwards. A similar arrangement was shown for winching rearwards, with the scotch plate under the front wheel, but I can't remember where the other end of the cable was hooked onto.
I always thought it was rather clever - the scotch plate has a "spade" underneath, which is forced into the ground as the vehicle is driven over it until the chain is taut.
As you say Keith it must have been a very late mod, because they're extremely rare to find. Here's one on a wrecked chassis I came across a while back.
