I am under the understanding that the "IH" logo was not used until 1946 or 47. It was also around that time that "Deering" was dropped and just "McCormick" was used above the Farmall decal. "Cultivision" seems to have been part of various promotions and may, or may not have originally been on your tractor.
I think that "Farmall" with "McCormick-Deering" above it, without the "IH" logo on the hood is correct for your year tractor. "Cultivision" is your choice, either way can be correct. That would be the straight Cultivision, not the wavy style. Wavy style is for Super A.
