I believe that Roland owns the documentation that has survived. That doesn't mean that he has everything.
I went through the files at the DeTomaso factory back in 2002 or 2003 to see what they looked like. US-era Panteras had rather little information - color, start date, finish date, and not much else. Then again, there weren't a lot of options available either.
Simply as an anecdote, there was no info on Amerisport cars, as the factory didn't consider them factory cars.
The 80's cars had a little more info - interior color, with or without wing, and who the car was sold to.
In no case were there 3 or 4 sheets like Mark mentions for the Geese.
