That RR @ Southern is basically your car if new/restored. The tags are very similar. The only visual difference is a shifter on the column or 3 pedals & a shifter on the floor. Trying to match colour to a 52yo sun faded/old interior isn't wise. Go off the fender tag.

The seat pattern in post#4 is not stock, redone in a non-stock pattern. The pleats are going the wrong direction, tho it does have the proper medallions.
The seat pattern in #5 is correct, for the upscale bench, (which I think is stock in hardtops). The coupes came with a taxicab seat, but the decor group upgraded the seats, among other stuff.
It does look like the medallions are missing in #5, meaning they have likely been redone too.
