That's it. It is a Volvo.
The windshield shape and door handles are also identical. Nobody is going to scratch build scalloped door handle pockets like that.
Notice also the door hinges. The two upper hinges visible on the Volvo are in the exact position as those on your truck.
So is this truck a Volvrolet or is it a Chevrolo?
Well, actually... It's probably not a Volvo-mix after all. Got some more info from a Swedish Vintage Truck forum, and according to the info there the chances of the cab being Volvo made is pretty much nonexistent. The similarities between parts is according to their experts more likely to be fire engine specific rather than volvo specific, and the cabs were most likely built by various coach builders around the country after the trucks came here as flat face cowls. Gonna have to see about finding that manufacturers plate...
