Ok, MOSTLY nos.... the bearings/cages are not, but they are in good shape. The rest is as-found, I haven't cleaned or polished them at all. They have shelf wear, so they look more like well cared for, but used survivor parts. The black stuff I think is a result of theplating process, or maybe some anti-corrosion stuff, I don't know. Still on them after 100+ years! They have no signs of having been used. $85 shipped in the CONUS.
