No clue if there were manufacturing differences or what not, case on the left is shiny and the seam is a little uneven, is it real?

I bought a 1977 video pinball system by Atari today and the vinyl sticker on the front is peeling up. I was just curious if anyone had some ideas on fixes to this from their own experience. All help is greatly appreciated.

Would I be able to hook up a 2600 without needing an RF adapter if I have a coaxial port on my TV? There’s one at an antique shop that I’d like to test, and I’d rather not have to buy an accessory if I didn’t have to. I’ve included a photo of my TV’s connection ports for reference.
