This is the only pic I could find - RM21 in "Omaha orange" - I know I've seen multiple pics of the H2S interior in one of the A12 cars, but can't find pics.
No seat medallions, so I'll "assume" Legendary seat covers - all H2S fender tags show A4 UDF.

I have tag info on 8 RRs w/H2S interior - A4, B3, R4, 2at R6, Q5, 2at 99
The Q5 car is 9A297xxx sound like yours?
