“GT” emblem & grill’s black background paint sheen Q

Time has come to detail the little stuff on the 67 Dart. Black background of “GT” emblems and grill are stone chipped and weathered. Both grill and emblems had been touched up at some time in the past with a non UV resistant paint. I haven’t been able to determine if the black factory background paint was flat, satin, or semi-gloss.

I took a look at one fender emblem pictured in Year One’s catalog, and was not able to ascertain its sheen. Anyone have knowledge of correct black paint sheen to use?
