I'll have to see if I can find the address, there is a company out there that restores old speedos including repainting the face. I'm sure if you contacted them they would do the face in your unit if it's possible. I know of them from a friend who restores mostly Knuckles.

I learned all I need to know about life by killing smart people and eating their brains.
