I have seen special advertising bodies such as loaf of bread, shoe, foot locker, house, bottle and the one in the photo in my link.
Are there any of these special Model Ts left? I think a house maybe, how about the others??

Not sure what chassis this was built on. But it has to be one of the coolest ever built.
