early 911 production question

[SCWDP911]

I have been looking around and so far can only see that the 911's started production in summer of 64. Does anyone know an actual date of when 911 production line first fired up, or maybe the first one rolled off the line?

September 14, 1964. 356's were in full production.

First car was 300 007, it was a 901 model.

The next day 003 was finished. And, two days later 001 was completed.



Factory looked like this by 1965.
