It wouldn't be the first (yellow) Porsche 962 without livery: https://fastestlaps.com/models/dauer-porsche-962-lemans
Jochen Dauer, owner of the Dauer Racing Team - the last one to win with the Porsche 962 in Le Mans (in 1994 - as a private team!) - sold road-going versions of the 962 C for 1,5M Deutschmark back then, IIRC.

Great work by the way, Will. I really like the paint job!
