International Harvester

International Harvester built trucks and farm equipment from 1902 through the truck division's sale to Navistar in 1986, and produced some of the most rugged, simply engineered light- and medium-duty trucks ever made in America. The K and KB pickups of the 1940s, the L-line and Travelall, and the legendary Scout 4×4 from 1961 onward built IH's reputation as the working person's truck — and the off-road enthusiast's secret weapon.

The K- and KB-series pickups (1940–1949) are the most active restoration targets in this category, with dedicated communities of owners keeping these prewar- and immediate-postwar trucks on the road.
