i removed my original, working headlight bulbs from my 69 charger, and they look almost, if not identical to your GE's. however, i think they are Westinghouse's. i didn't blow the dust off, or try to clean them, but i'll bring them inside for a closer look. [where it is a "little" warmer. ] interesting comparison of lens flutes ! there are date codes on my bulbs so i will try not to ruin them when cleaning off the dust so i can compare my dates to those of your bulbs. i realize this is an apples to kumquats comparison.
