Welcome to the club.
The lids really don't paint well-the colors on them are porcelain enameled, not painted. That's a beast of a grill though. I've got one going on twenty years old and going strong. You might be best off hunting for a used redhead to swap out the manifold (to convert to propane) and get a real red lid out of it that way. If you do go that route, make sure your donor grill and the one you have have the same amount of flavorizers (5 or 13). It won't matter for the lid (those will be interchangeable as long as you're still on a 3 burner) but it will for the manifold. If you post where you're from people might be able to help you. Those look like cast iron grates, which will clean/season up nicely, and the frame and boards look to be in good shape.
If you have questions, just post them up, since there's a lot of knowledge here.
