All the sockets appear to be in the 100 year old age range and have various markings with one that is hard to read under the glaze.  One showed 75W 125 V.  

Some original dust from storage. Some minor chips in the porcelain.  All sockets have screw connectors for wiring.  All from the old inventory of a local appliance, lighting and radio repair shop now closed.
