As far as I remember, it was at least five companies supplying bodies for the 3 ton range CMPs.
The photo below shows such one body as on those dessert photos. I do have writen down the id-plates somewhere, but guess it is in my store.
And as mentioned, it can easily be mistaken for a GMC/US body, it even has the hatch at the rear of the body as found on those GMC bodies.
