So my employer wants me to restore this.

The shadow area on the grille where you would expect the maker's badge is shaped like the Autocar badge but one of the pictures has an International badge (3 diamonds with "International" on the horizontal stripe) within the shadow area. The general shape of the cab does resemble some of the Autocars shown in the Observer's Fighting Vehicle Directory (one of the first MV references I bought and still a very useful general book). The Autocar U-2044 is listed as using the Hercules JXD engine. Aginst this suggestion - most sources show the U-2044 as having an oil servicing tank body on the rear. I have no evidence of Canada using the U-2044, likewise no proof that it wasn't used here.
This is a first guess, certainly not a firm identification.
