The F-12 you're showing us does include International Harvester in the name. I've never seen Farmalls as being separate in any way from International Harvester, unlike Deering, Milawaukee, Morton, Hough, or other brands that they bought during much of the 20th Century. Anytime I've seen a tractor with the word "Farmall" across the hood, my first thought was this was an International Harvester-Farmall, espescially when the "IH" logo is right there for all to see.
