I would remove the name and a cold blue touch up and leave it alone. I would have left the name but it looks scratched from trying to remove. You could also shop for a Colt slide as all will interchange. There is a #stamped under the firing pin block before about 1941 that should match if the slide mated with the gun. I like it. If you do anything keep the original parts. It may have been buffed down as the serial # is really faint.
