1971 Dodge demon 340 4sd, factory roll back top...ever seen one like this?

sure that one was not a add-on later, or is it on the fender tag/build sheet?

I have owned 3 sunroof Demons over the last 25 years. Two are Super Blue and the 3rd, gold. The code on the fender tag is V3W for white and V3X for black. Yes, this is the same code a B or E would have for a convertible top. I will try to add pics of my current when I have a liitle more time. Thanks. Also, the owner of the Demon with aftermarket wheels gave me pictures of his car back around 2000 @ Carlisle. The orange Demon is from PA and one 1st in class 'A body Dodge 1971-76' from 2002-2005. The yellow Demon at the dealership I have't seen since the 1990 Mopar Nationals. Thanks
