Do you have this emblem on your 66 fish?

I had to chuckle when I saw this post because it reminded me of the same question left unanswered since 1973. When I was in college my good friend had a red 66 Barracuda. We often parked my 64 and his 66 next to each other. One day we came out and there was a yellow 66 parked next to his. We went searching for the owner. A girl had aquired the car from her Grandmother and she became a friend of ours because of her car. One day we noticed that her car had the Valiant emblem on the grill and his had the fish. The only other difference between the cars except color was that his had an "Economy Gauge" and hers didn't. I suggested that the difference between the emblems was probably based on production date so we checked the serial numbers. Hers was later than his! Same plant. So we shrugged our shoulders and forgot about it. Until now!!!
