I wouldn't be too upset with scratching it up. Much like Prymer said, you can buff it to remove any "excessive" scratches but in reality it's supposed to look banged up to a certain degree.
By the by, the Heiland I have still has the innards because I was scared about prying them out. I've removed the attached brackets but where the "light bulb" would go there's the electrical mechanism that doesn't want to come out.
Any hints? Were you able to hollow the Heiland out?
