British Studebaker US6

[Jan Mostek]

And at the end, I would have two questions, perhaps some Studebaker experts would know:

1. On the picture below it si visible some box behind the cab. Is it an additional fuel tank (because of expected long routes of tractors) or some tool box? Was it a standard fitting for the tractors?

2. Were all tractors with rear wheel drive only or were made also tractors with all wheel drive?

Thanks in advance for your comments
