International Harvester in World War Two / WWII
1902- 1985 (For combined farm
implement and truck operations.)
Navistar International continues to make what used to be IH trucks today.
International Harvester started producing motor vehicles with the
"Auto Buggy" in 1907, and built the first 100 at the McCormick Works in
Chicago, IL, before moving production to Akron, OH in 1908.
Production moved once again in 1922 to Springfield, OH with a second
plant added in Fort Wayne, IN a year later. The 13,622 M4 Half
Tracks were built at the Springfield facility from October 1942 through
January 1944. Most of the trucks built by International were used
by the Navy or Marine Corps or became part of the Lend-Lease program.

The business end of a Mark VIII aerial
torpedo. The Mark VIII was also used by PT boats but would not
have the ring around the propellers. International Harvester
produced the Mark VIII along with Pontiac Motor Division of General
Motors, The Naval Torpedo Station at Newport, RI and Ameritorp

Due to the fact only 1,123 M-1-4 trucks were
built this is a very rare example. The Navy took 232 as cargo
trucks and 891 as ambulances.
This International Harvester M5 high speed tractor is from the
collection at the National Military Historical Center, Auburn, IN.
