Paul, thank you very much for your thoughts!
I am really clueless regarding the age of this piece, so you may very well be right with your 1930-40 estimation.
I have looked through Pamela's site, but coudn't find this design.
There is quite a lot of wear to the polished base, but that may not mean very much.
It was the wonkiness which made me think it was probably a little older than Art Deco period...
