52 years after introduction day, only one '69 Z/28 with other than white or black stripes is known. It's burgundy with red stripes, an early Norwood build per the color chart at that time.
There are very few Z/28s with non-normative combos; silver with white stripes and Le Mans blue with black are known. Special paint was noted on dealer paperwork but not defined. Sometimes noted on production broadcast copies, very rare to have those.
