Antique Lamps My Mother Bought A Set Of Antique Lamps..how Much Are They Worth?

My mother bought a set of antique lamps..how much are they worth? - antique lamps

I do not have to search the web for over an hour and can not find a photo of them. These lamps are electric and have a crystal ball is yellow or orange light and has a model of the grapes and oak. At the base is the inclusion of L & LWMC 1971st Both the lamps work, but the man who sold us for $ 5 pair had cast a shadow, they were very dusty. If anyone can help us a picture and what they sell for ... I appreciate it ..... Thank you!
