916 development question, for the historians with German roots Options

[larryM]

just got Gooding's 914 book (Enthusiast's Guide, 2016), which has some interesting historical stuff on the 916 & GT cars;

it prompts this question:
(which probably requires the knowledge of you few 914 folks with Germany roots or current contacts to those who worked at Zuffenhausen in the '69-71 time period)

When did the factory begin development of the 916 variant?

i.e., start on the design of the different body components & chassis improvements, and decide on the powertrain, etc??

and when were the first prototyped "new" components begun & finished for trial fit on the the prototype chassis?

(and where were they made? (?-Werks-1? - or ?)

Who was responsible for the decision to do the 11 finished cars for the Paris show (October 1971)?
(edit update: looking at http://916.dingianni.org/Info/, we see that 4 916s were finished & gone to new owners prior to that Paris Show date, so Gooding's statement is a bit misleading)

and who decided to kill 'em?

inquiring minds want to know

TIA

Will someone please tell the story of this 916 in Blue and cork leather? My favorite color combo. I had a 79 Targa SC in this color combo. There where pictures of
Wolfgang in Europe with it when it went back to Europe.
