Eventually, International Harvester would become a massive global ... Its “Emeryville” series of 1940s and 1950s cabover models had earned a reputation for reliability and toughness.

International Harvester has been off the market since 1985 (reorganized as Navistar), so it's not exactly surprising that most of its trucks and agricultural equipment are now largely forgotten.

And at the very tippy top of the triangle comes the International Harvester Scout, a happy-go-lucky trucklet built from 1961 to 1980 that only the most devoted 4x4 enthusiasts know about.
