Restoring Arnolt Bristol # 3075 need help

[Restoguy]

Hello everyone !

I am currently managing the complete restoration of a 1954 Arnolt Bristol, chassis # 3075. I have a few questions regarding this car, as it was heavily damaged at some point in it's past life. The car is currently completely disassembled, media blasted and coated in epoxy primer. It's about to undergo major sheet metal fabrication and replacement. In my research, I've noticed a few different grille shapes and nose opening shapes, and I'm uncertain on what this car is actually supposed to look like. Were all '54 cars identical in the nose and grille, or was there a difference between the various models? I believe this particular model is a D, = Deluxe. Can anyone identify for certain what the grille and nose opening should look like on this particular car?
Also, is there a color code available for the "Post Office Red" on the exterior, and the grey color on the engine compartment?
I'll have many questions regarding this car during it's restoration process, and hoping to find help with locating parts as well. Thank you everyone!
