Moulded Glass Shade Floor Lamp

This floor lamp has been in the family all my life- My parents seem to have had a love of lamps. This one is something they bought shortly after they married in 1935- and I expect it was second hand then- most of what they bought was. The shade is moulded glass with a butterfly pattern around the side. The filigree shade base is a pewter color- I do not know the metal. There are trim areas of brass as well, making it a nice two tone blend. The base has a marble top with the gargole type figures holding it in place. I was so surprised and pleased to find out so much about my reverse painted hanging lamp that I thought it would be nice to find out about this one as well. This lamp is very heavy.

Any information at all is appreciated- including maker and value. I will not be selling the lamp- it is valuable to me regardless. Thanks for all help.
