This is an early O.C. White Co articulating task lamp. The lamp still has it's original green porcelain enamel shade which is in great condition. The lamp has been mounted to a piece of new plate steel so it can be used easily as a table lamp without actually screwing it in to your table. It can be mounted in a variety of ways if you remove the plate. This came out of a Montreal machine shop. Not signed but attributed to O.C. White Co.
