At the turn-of-the-century, most farm vehicles were made with high wheels for better ground clearance on rutted, rural roads of the time.  International Harvester Company (IHC) began building farm wagons in 1907, and used high wheels with solid rubber tires.  As roads improved, low wheels with pneumatic tires became more practical and, in 1915, IHC offered both options on some wagons.  Gradually the high-wheelers were phased out.

The initials “M-W” indicate this model is a motor truck with a water-cooled engine.  1912 was the first year IHC offered a water-cooled engine, air-cooled being standard in previous years.  Panel Express trucks were highly versatile.  The family could travel together to church on Sunday or, by removing the back seat, a full load of farm products could be driven to town.

In 1984, International Harvester sold its agricultural business to Tennaco, a subsidiary of Case.  In 1986 International became known as Navistar and concentrated on building trucks, buses and engines.  International Truck is Navistar’s flagship vehicle brand.
