My 39 1 1/2 ton (Rusty) came from factory as far as I can see with no vin plate on cowl or anywhere else on cab. Never a Vin plate riveted on cowl like it's supposed to.This rig was used by the Wa. State Forest service for hauling (2) horses into the back country.
Do you see any rivet holes on upper cowl left or right? If not, 39 COE may have come off the factory line headed to some state or federal position where they do it themselves is my guess. Is there anybody out there that really knows for sure? freddy
