That truck brings back memories!! My mom's great-uncle had a '38 1-1/2-ton with a corn-sheller mounted to it. It was a "Running-when-it-was-parked truck back in 1960!! I used to act like I was driving it,(I was 4'or 5 years-old),every chance I got,at least until the wasps took-over! It sat until their estate auction in the late'70's. I think it sold for $100.00! The body was still in very nice shape-no dents,just surface rust.
I'd love to find a truck with a corn sheller still on it-any brand! There used to be several operators around here who custom-shelled corn. Of course, when they all quit, I was still too young to be thinking about buying any of their equipment.
We also had a couple trucks in our area with feed grinders on them. Haven't seen one of those for quite a few years either.
