Does someone knows where WacKEDmaN's nordschleife comes from ?

I'm looking aroung to find where the model uploaded and removed by WacKEDmaN comes from to contact the author.
You can find it here https://beamng.com/threads/nordschleife-reuploaded-need-help-to-improve-quality.35143/, reuploaded by DAYTONAAAAA. I've asked him and await his answer.

Does someone knows that ?

Thank you !

 

I believe it was from Race 07/GTR Evolution

 

Thanks !

If someone can confirm or infirm...

 

I know that some Nordschleife port was from rFactor (2), but no clue if it was this one

 

Thank you for the input, would you be speaking of the mod maintained by DJC & Tosch (https://www.bsimracing.com/rfactor-2-nordschleife-v2-01-released/) ?
