The Evolution of Automotive Design in the 1930s

The Evolution of Automotive Design in the 1930s

The other day I received a very nice note from Terry Jacobs, the owner of an absolutely beautiful 1940 International Harvester D-2 short bed pickup. As we traded thoughts on trucks, he mentioned that he had authored an article that had been published as part of B. Mitchell Carlson’s “Triple Diamond Treatise “, a regular series in Vintage Truck Magazine. The article was originally published in the December 2015 issue, and with Terry’s permission, we have reproduced it in it’s entirety here.

You will find the article to be an excellent read, as it provides some excellent insight as to how the design of the International Harvester D-Series came about. I have also added the photo of Terry’s D-2 to our D-Series gallery along with several new images. I try to select images that provide good historical information on our trucks and any accessories that might have been used.

L and R-Series Library

L and R-Series Library

For those of you that used to frequent the previous website – “Restoring Cornelia”, I have great news. I just completed transferring the L and R-Series documents from the site and have created a new “R-Series Library” page for you (contains as much L-Series information as R-Series, though).

In the new library you will find the MT-97 Parts Catalog, an Inter-Sub Manual from 1959, the CTS-11 Service Manual for L-Series Trucks with the CTS-12 R-Series supplements, a Carter YF Service Procedure for rebuilding the carburetor, the CT-62 L-Line Product Information No. 2 Sales Guide, and a Wiring Diagram for R-Series Trucks.
