Valiant Barracuda

So I've seen a ton of pictures of the 64 Barracudas running a Valiant emblem just under the trunk lid of the passenger side, I know the history of the Barracuda and understand its part of the Valiant family. In fact my 64 Barracuda was registered in Las Vegas as a Valiant. I want to know witch Barracudas had the emblem, was factory thing or a dealer add on, should my car have it ?

My computer broke again so back to using just my phone to check, sorry for slow response and thank you for any information
