Yeh Ray,
It appears as though the "I" emblem and the plastic trim piece are as correct for later Ingersoll tractors, not the CASE tractors.
The Orange and yellow "CASE's" had a black painted grill all the way to the top of that area where the headlights mount. It always bugged me when people repaint those hoods orange, or Power Red, and don't paint the grill area Black. I usually paint the whole hood Power Red, then tape them off and get a good coverage of Black to cover the grill area. I usually tape the back of that grill area tight with newspaper, or some kind of paper so the black does bleed through to the inside of the hood. That makes them look that much sharper when done.
This tractor above would have been ID as a CASE and model with the Decals.
I am not sure that Case was using a CAB that early in production, but it fits and looks nice, so who cares?!!
