I seem to have a different experience than what several others are claiming is correct. I have a 1952 3100 that was manufactured in Oakland California. It has never been out of California. It has the original door pillar tag with the engine number as ID. It matched the engine in the truck and the title (aka pink slip in CA ) when I purchased the truck. I purchased the truck from the second owner and she purchased it from her neighbor. The tag had never been changed.
