This set is likely from the 1960’s and might be something you need for your restoration. The knobs are either solid cast copper or copper plated brass. The rosettes are pressed brass and appear to have slight traces of copper here and there. The brass and copper of the knobs and rosettes provide a pretty contrast.
There is a third hole in the rosettes that was for a push button lock. One knob has some tiny dings around the perimeter and both have a dark area on the perimeter that could be buffed out if you wish to do so. If not, just mount with it facing down and you will never see it.
