I don't see a mark. A kind ebayer wrote me to say it is late 1930s Rumrill. This lamp works but rewiring highly recommended - see photos of cord. Stands about 17 but that is slightly adjustable at the branches are wired and can be bent. I have two similar lamps listed from the same estate.
Please see my other listings. One of the others is a Roseville vase.
Some of the glass petals / leaves may be missing or detached or damaged - please examine the photos carefully to assess.
