Well unless you (or someone) have a 1980 M439 optioned car with serial "0001"or "4272" which would be the first and last one of the 408 made... who knows.
If there was a data base that has all 408 listed it could shows which one is which.
I check Simon's Porsche 911 SC Site Registry
Simon's Porsche 911 SC Site and only 34 are listed as such with the first one at "91A0143269" and the last one at "91A0144113". That is less then 10%.
I'm sure somewhere Porsche has the listing.
Good Luck
