Vehicles used by Dutch Prinses Irene Brigade

Another piece of the Artillery Tractor puzzle:

Rier view of a FAT, census number H5558308. I thought that solved it, but then I read this:

"H 5558176 - 5558375 / SM 2546 / Tractor 4x4 F.A. / C291Q / F-GT

However HISTORIC MILITARY VEHICLES DIRECTORY P. 52 has a photo of a Chevrolet FAT marked up as ‘H5558307’!"

(see: http://www.btinternet.com/~gmhistorian/fordlist.htm )

Any thoughts?
