Re: Bavaria Rural Police Luger
The inscription appears to have been put on with a DC discharge pencil. It is more like a tiny arc welder in that it burns the marking into the steel. Normally you can see where the pencil was put down and picked back up by a tiny arc mark. It is commonly used on hardened steels to mark them. The electric vibrating pencil marks by stippling the steel and leaves a rough finish. It will only work on soft metals.
