1971 demon interior paint finish

Hey all,
I can't seem to find this information on here but I'm trying to find out what finish that the dash, doors and sail panels came in originally on a 71 demon.
The fender tag shows GB5 exterior and GB7 for the interior color and It looks as if the dash was a flat finish on the little I can find from removing the windshield.

Would the doors and sail panels be painted gloss like the body or were they flat as well? Everything is painted black right now so there's no signs of the original finish.

Oh and would the top of the doors have matched the exterior color or be the same as the rest of the interior?

Thanks in advance,
Carl
