Scratch remove technique needed
 
Ok, so I have(well soon to) have a 7 inch 1940s set, but one problem is the screen is kind of scratched up and it doesn't seem to be deep cracks, but visible surface scratches and I was wondering if anyone knows how to get off these scratches without replacing the screen.

You pretty much need to wet sand the surface level. For deep scratches I'd try strating with 100-120 grit paper, then working your way down to 1000-1200 grit. Follow that up with some Novus #2 polish, possibly follow that with Novus #1 if you're a perfectionist. The sand paper grit you start with depends on how deep the deepest scratch is. You can always start with finer paper, but then it takes a lot more elbow grease to get the deeper scratches out. I use blocks of firm foam with the paper glued on with 3M headliner spray adhesive.

Yes, start out with the finest grade of sandpaper that you think will remove your deepest scratches. This article describes how I polished the Lucite screen cover on my Admiral 24C15 (scroll down to "Restoring the Screen Cover"):

I started wet-sanding with 800 grade paper and ended with 2000 grade, followed by polishing with Novus #3 and #2. My cover didn't have deep gouges, just a lot of surface scratches and a cigarette burn.

The first time I did it on an Admiral 7" screen I was sure I was ruining it. As you bring it back-up with finer grits it ends-up looking beautiful. Just be sure to sand the entire surface EVENLY and get the scratch all the way down with the rough grits.
