There are two knobs in this bag of twenty-six that are not painted, and they have a copper finish. I think these are actually all midcentury knobs by the style of them, but someone painted most black. You might be able to boil of the paint (use a little baking soda and a pan you don't care about), but there's a failrly good chance the original finish was wearing, and that's why they were painted. Most do not have their machine screws, which are easily found at the hardware store in the length you need.
