Antique Burl Wood Lamps-Matching From Same Tree With Same Base-nobs and tops woo

I have these burl wood lamps with the burl injury and looks to be made from same tree. They have green felt on the bottom but can not find any markings. They appear to be older maybe made prior to the 1960s. The bases are cut from the same trunk since they are the same shape and match.

Please let me know if you have any idea of what these are and who made them. Also, looking around the internet looks like a price without shades looks like a good price range is maybe 150 on the low end each up to 3500 each if they are some type of collector lamp made by a famous designer. Any idea on value would be great if you recognize them and really appreciated. Thank you up front.
