I suspect that in the thirst for raw resources, there would not be very much loose scrap left in those parts of the world. Their scrap guys are even showing up in this neck of the woods looking for large quantities of scrap metal, and shipping it back.
This thread made me recall that I had a 20cwt trailer that was marked for Aid-China on the data plate. The data plate was riveted upside down, I suppose so that when the trailer went to the bottom half of the world it could be read.
I believe the date on the plate is Oct of 45, so the aid is post war.
