No Fender Tag or Broadcast Sheet?

I just located 2 Demons for sale, 1 is a 72 /6 manual trans. car, the other is an H code 1971 340 car. The 71 is an original purple car. It looks like it had white stripes and a black vinyl top, but there is no fender tag or broadcast sheet in the car. Has anyone ever seen this combination? Is ther anyway of finding out what the car came with originally beside finding previous owners.
Thanks Warren
