 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 Corporation.   Author's photo from the Air Force Museum.

 This was one of the most complicated and difficult weapons of WWII to build, containing 5,222 individual parts and 1,225 assemblies.  Author's photo from the Air Force Museum.

The International Harvester M-1-4 1/2 ton 4x4 trucks were used extensively by the US Navy and Marine Corps.  From the collection at the National Military Historical Center, Auburn, IN.  Author's Photo.

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.  Author's Photo.

This International Harvester M5 high speed tractor is from the collection at the National Military Historical Center, Auburn, IN.  Author's Photo.
