We have had this 1960s Adjustable Brass Floor Lamp before, however never in solid brass, and we are still unsure of the designer. I'd say Gerald Thurston for Lightolier, but it could be Robert Soneman or Koch and Lowy or Chapman. It has a thin, solid brass base plate with a brass stem which connects to the telescoping brass stem that loops over the shallow brass shade like an umbrella handle. Lamp is in very good condition and measures 40-54"h and 16" across. This one has been rewired and fitted with a dimmer switch. SOLD.
