Dear Mr. Ferrari,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series Publications and Issuances and the series Reports and Technical Documents Accumulated as a Result of Ordnance Contracts in the Records of the Office of the Chief of Ordnance (Record Group 156) that contain records related to International Harvester during the 1940s and that may include some information related to your research. These records have not been digitized. Please contact the National Archives at College Park - Textual Reference (RDT2) at email@example.com for access to and information about these and similar records.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2. We apologize for this inconvenience and appreciate your understanding and patience.
You may also wish to contact the Wisconsin Historical Society to learn more About the McCormick-International Harvester Collection and to see if they can assist you further. The University of Guelph also has an International Harvester Collection that may be of interest to you, and Cornell University has Selected International Harvester Company documents and agreements that might also be relevant.
We hope this information is helpful, and best of luck with your research!
Dear Ms. Saler,
Thank you for responding back with the leads and pointing me in a direction.
I have several different IHC military vehicle parts books that IHC manufactured during the second word war. If I am able to cross the military numbers to vendor numbers, I should be able to find these tools through tool collectors, flea markets and other sources; adding to my IHC tool collection.
I will probably have more questions as I research and progress.
