Blown glass florist vase.

Another slow day glass piece. It is about 11.75" high x 5.25" at its widest. The diameter of the base is slightly larger than the fluted top. There are fourteen vertical flutes on the inside of the vase which end in six flutes at the top. The bottom has a ground pontil and lots of ripples that make it look cloudy in my image, but that is reflections from the ripples. I think this may be an older piece but can find nothing to compare it to. Possibly American florist ware from the 1920s-1930s? I have not seen anything like it before. Any thoughts on this one?
