I have been doing radio restorations for early cars (Packard, Pierce Arrow, etc... from the mid 30's) and have found something interesting about the color of the wrinkle paint on the Philco sets (some of the sets were Atwater Kent) . I would swear the original paint was black but on very close inspection, the actual color is very dark brown as shown when removing some of the trim parts (like the Manufacturer's name plate). The paint must oxidize over time and turn darker making the dark brown turn black. Most of the time it is best to STRIP the original paint, but if you do, you will need to apply metal primer so the final color coat will stay on the part. MSC Industrial Supply supplies the correct color of wrinkle paint in 12oz Aerosol cans. The MFG number is 80860. Their catalog number is 89773899. UPC is 024821808607.

Also, you can re-use original grille cloth (if it is in decent shape) by misting the cloth with a spray paint that closely matches the original color. Be sure to LIGHTLY coat the cloth so you don't clog the fabric. I sometimes washed the cloth prior to painting but some of the time the cloth would fall apart. Be careful not to ruin the cloth.
