International Harvester has a long-standing history in the city of Fort Wayne, producing the first trucks at the local plant in 1923 and going on to roll more than a million off the assembly line.

This engine is part of the Green Diamond family that powered International Harvester trucks from 1934 to 1949. While they're far from expensive, these old KB trucks are definitely hard to find.

The company was renamed Navistar International in 1986 and now focuses on trucks and engines. Norris said Harvester and Navistar vehicles are welcomed at the homecoming’s truck show.

International's light- and medium-duty legacy goes back to the early 1940s to models like the K and KB Series. These were followed by the L Series in 1949 and the R Series in 1953.
