A few months ago we sold two floor lamps noting that there were no markings on them. We now have another reading lamp and it is marked...twice. The base is marked “J.L. Stuart Mfg. Co. SF” (San Francisco). The shade is marked “Sandel Manufacturing, Chicago, IL” The lamp has a “C” of chrome supporting a 10” diameter shade with a stepped chrome top. The base is a square wood base inlaid with chrome “speed” lines and sits on chrome corner feet. The bottom of the pole is a column of black enameled metal with two “speed” bands topped with a chrome section. The shade swivels to direct light for reading. The lamp is 50” tall, has been rewired and is in great vintage condition.
