1968 Gottlieb Royal Guard Backglass

Hello Everyone,

I'm currently working on bringing a Royal Guard pin back from the grave, and I was hoping for some advice/opinions on how to go about fixing up this backglass. Attached is about what I'm working with, you can't see it, but most of that paint is actively peeling. My questions are thus:

What kind of hope do I have for repairing this? Is there a type of go-to paint if I want to take a swing at it? Should I be looking into just scrubbing the glass and trying to get my hands on/produce a mylar for the backglass?

As a related question - does anyone have a decent resolution photo of the backglass? All I can find on GIS are low resolution, or have camera glare/angle problems. Whether I try to make my own mylar or try to repaint it myself, a solid reference would really help.

Thanks, I'll look into that. I'm pretty dedicated to fixing this whole thing myself (stress release/health thing), so anything anybody can tell me on how to go at it is very welcome.

Thanks for the advice! Right now I'm looking into doing some digital work and trying to print a mylar sheet of the backglass image. I'll miss out on some of the things that are supposed to shine through the paint to show a number or text, but it will at least light up well.
