This 1925 Model AC "Bulldog" truck is
similar to what the company provided to the British and US Armies during
WWII. British troops nick named them "Bulldogs" because of their
toughness. Note that the radiator is located just forward of the
firewall and the cooling fan was driven by the flywheel.
Originally the Model AC came with hard rubber tires and was introduced
in 1916. Author's photo from the National Automotive and Truck
