FYI - 59 production rate in Nov. 58
I shot some pictures of 5 junk yard Squarebirds that I will post soon. I included pictures of the data plates and found that the VIN number on one of the 59's is only 383 higher than mine. The date code on mine is 10L (a Tuesday), and the date code on the junk yard car is 13L (a Friday). So that's 383 cars produced in 3-4 days.
