must-have ! VintageWaldorf lamp with finial

This is a lovely light fixture that was one of several I salvaged a few years ago. The base appears to be brass and the light sparkles beautifully in the sun. Several other lights salvaged from the same source appear to be the same model as those used previously in the Waldorf Astoria. I believe it has a brass mount base and then a brass finial with a cut or pressed glass cover. Please check photos for signs of wear. I do not have many details on these lights and would suggest having them professionally rewired. While these are certainly vintage I am not positive of their source. I'd love to find this a good home so open to offers. Photos are a part of the description and include measurements. You should be able to see the maker marks in many of these. Offering no-cost shipping with USPS which is reflected in price. Please let me know if you have any questions.
Please feel free to share any questions and I will my foremost to answer.
