Many thanks Jeff! In this specific case, I'm restoring a Dearborn Mach1, built 10/08/69.
It's difficult to know for sure, yet the pictures you kindly provided appear to show chrome around the perimeter of the sport lamp grilles. I have several pairs and find these scenarios:
(1) Chrome front and chrome perimeter with black paint everywhere else
(2) Chrome on the front only, black paint everywhere else
(3) Chrome on the front only, argent paint everywhere else
I'm trying to figure out what scenario is correct for the above stated application and build date/plant. Perhaps the differences noted above simply reflect multiple Ford sources for these sport lamps?
Thanks.
