Cigarette Lighter on '66 Barracuda

I've been trying to figure out whether the cigarette lighter on my '66 Barracuda (mounted under the dash below the radio) is original or not. I understand a lighter was an option on these cars, but that they were not too common. The build sheet is under the back seat, but I'm not able to get a good look at it to see whether the lighter is listed or not. I could not find any manufacturer markings on the lighter itself.

Could someone post a photo of a lighter known to be original or at least describe what it should look like or where it would be mounted?

I plan to remove it if it isn't original.

Thanks.

Steve
