IHC also built many thousand armored Halftracks very much like the White M3, and rebuilt a goodly number of M4 Sherman and M3/5 Stuart tanks. IHC also made air-drop / PT roll-off torpedoes.
For this thread, here's a bit from (Navistar) corporate historical archives which should help muddy the waters re IHC "non-Willys-Overland or Ford Jeep" vehicles.
Trucks and buses came out of a half dozen plants in near that number of states under at least a hundred different contracts. Individual contract language would have "ruled" but at least some vehicles destined for the Navy which were spec'ed variously as "Grey, Navy Grey and Battleship Grey."
Construction and traction equipment was pretty much OD, as far as 'have been able to research. "Olive Drab" --one long-term veteran worker at a Construction Equipment plant claimed (at least 35 years ago):
"We mixed OD using Farm Tractor Red, Construction Equipment Yellow and Black, colors which were in our plant inventory."
