This vintage item has no markings, it has the geometric design on the pressed metal ceiling plate. This has the original chain, wires and socket, it should be re-wired in order to be used. This measures 6-1/2" wide across the ceiling plate and is 28" long from the edge of the top to the bottom of the bell for the socket. I see one small screw is missing to hold the shade in place, but no other issues other than normal wear, no damages. This does not have a shade with it, but the fitter collar is 2-1/4", so it would not be difficult to locate a shade for this fixture.
