Well, In 1.5 hours of research I have found that this is D450-37 series (could be a couple others but that is a generic enough label till I get the pics from my dad this evening). Seems they were only made for 2 years 1952 and 1953. Most were actually sold to the US military. The truck's interior is gone which probably means the floorboards are rotted out. No big deal on those, that is a simple cut and weld in. From what he says there are no dents in the truck and it is a dump truck style single axle at the moment. It has not ran for 8 years but it ran fine when the farmer parked it. He paid $1000 for it. I have no Idea if that is a good price, average, or too high for that truck. Does anyone have any Idea what these trucks are actually worth? I know if this would have been a standard 450 the price would have been about right but I have no Idea on this diesel. Until the other day I did not know GM put a diesel in the Advanced design trucks at all.
Here is where I found my data.
