I'm not a Dodge expert so don't know your answer off the top of my head. Should I be looking for interior or exterior photos to try to find an answer for you?
If you were trying to include a photo to show us the puzzle, perhaps this guide on adding photos will help. http://www.mapleleafup.net/forums/showthread.php?t=19
Your location shows as "China", is it possible that it was a piece of equipment used by the military in the China theatre or something added for use in China post-war that would have been there long enough for the shadow to fade/form in the paint (or do you mean that there is no paint where the object was located)?
