There is no way to know who made these lamps !! There were many made !! You might look on the bottom and see if there is a foundry mark or name !! A foundry would have cast all the parts but I doubt they were assembled there !! Lighting companies usually just ordered all the parts for a particular style lamp and they only assembled it ,,put their tag on and sold it to retailers !! There are hundreds of different styles of these floor lamps and only rarely will you find a makers name that is known !!
