273 commando V8 badge

Hey guys, I was wondering what was up with the "Commando V8" badges I've seen for sale. Which cars did those come on? I'm rocking the 273 commando in my '66 barracuda, but Ive never seen any other cudas with a badge like that. I just have the standard "F-S" badge and "barracuda" on the front fenders.

Hmmm
