I have this Dodge micrometer scale. It is obviously been painted but the patina tells me that it was an older restoration. I have seen this scale refurbished in nickle, brass, and in some cases partially painted. The user knob has the paint wore off and is nickle. The paint job is sloppy in that there are spots where the paint is on the marble base. My question is: should i strip this paint off? my fear is that it is not completely nickle. I don't want to devalue it. I like it as it is, but I also like the idea of it being in original condition. Please help
