Anders - great work!!! You tracked down alot of great stuff!
Productivity: this would be very interesting to track down. The only variable I can think of that might mess it up would be if there were two production lines running in parallel. But this kind of info must be out there somewhere.
I do recall reading that Ford did very well in profit terms on the Squarebirds...The design and tooling had not been too expensive and the assembly was not bad...I have a feeling that $1000 per car was not out of the question.
