Painted!!? That? Nice bike, 52, and it looks to be in very good condition. Don't worry about the paint. Flake off the bits that bother you down by the fork ends and cover with paste wax. Clean the whole frame with warm soap and water, dry thoroughly and then some good wax to protect it.
As we like to say here, it is only original once. If you want a bright, shiny new paint job, you can get one of those on a new bike. But part of the charm of a vintage bike is its honestly earned scars and patina.
