The ACME is silver plated directly over the 688 brass, no substrate and 200 microns deep.....The brownish color is sulphur from air polluton and not copper leeching through or oxidation as silver doesn't oxidize at room temperatures.......I have some glorious sounding Switchcraft panel mount IEC connectors from fifteen years ago that have turned almost black with the sulphur.....
