I don't think the color is correct...
If I were buying it and were planning on having it judged in NCRS I would have someone (who knows) check the color, as it is one of the most difficult hues to get correct.
I did multiple sprayouts and sendouts for approval from the NCRS paint judges for the Warbonnet Roadster I painted prior to the 2019 NCRS national show.

If I realized it would look so good I would have bought the HARRY MANN 72 LT1 A/C coupe with tons of paper back in early 2018.
