There was a 50/50 chance, Mike ... ... it is the Ford.
It is very difficult to keep them apart, if the logo is missing. The Ford has a small hole at the end of the bumper. The extra picture shows the light falling through this hole onto the wheel.
Cab 13 from 1942 is correct, the version I would say is the 115" wheelbase F60. I judge the wheelbase to be a bit too long for the 101" F15A and a bit too short for the 134¼" F30 or F60. This actually would be a second clue for the Ford, as Chevrolet did not use the 115" wheelbase.
