I have restored several original WW 1 vehicles The smaller is my 1918 Dodge Light repair truck. About 1000 built for the war effort and only 6 known to exist. The larger beast is my 1918 FWD model B Mobile artillery Repair shop . The US Britian and Russia bout these. Total of 14,000 trucks and about 3 dozen exist worldwide. Wheels were done by Canton Bandag who did the Overman Cushion tires.
