My name is ***** ***** I would love to help. There are no photos that rode along with your original inquiry.
The next step would be for me to see pictures of the lamp and any marks or labels so that I can get visual clues of the maker, date, style and value.
Use the Add Files feature on your screen to add pictures (one at a time is best) and I will be able to complete my answer, thank you!
I got the picture here of the bottom. Just do whatever you did again for the a pic of the whole lamp.
The Add Files feature works by sending one at a time.
