Broadcast sheet mysteries

The Windsor plant did odd things with coding that I have not heard of a way to decipher yet.

Also interesting here with your colored sheet - the paper evidently stuck in the printer & its started printing the data on it for what appears to be ?H23B1R100137 - the next car in line at that printer station. A close up of that part of the sheet would be cool & may make it possible to clear up which part of that line was printed over another.

As far as this goes;

The car was built to USA specs,exported to the US and sold new in the mid-west.

Cars built in Canada for the US & cars built in the US for Canada are not considered 'export' cars. The Y09 (export) sales code only refers to cars ordered from overseas.
