Just over 8 1/2″ wide, 3 1/4″ high and 6 1/2″ deep including back portion of clamp (not nut). Lamp itself is about 3 3/4″ deep without clamp portion.
Metal shade that almost has a Bronze tint to it. Works like a champ with original cloth cord and White end with Deco design. Pull chain operation. Heavy duty squared clamp at back make this lamp much more flexible to be easily used for other illumination such as over that great Maxfield Parish print you have languishing in the dark. Made by Emeralite with partial decal label on back.
Wing nut clamp starts with about 1 3/4″ opening and adjusts with original felt pads on all sides.
Exterior on shows since of much less than normal small spots of wear but excellent overall.
