Her head looks as though it has a head-dress ring type thing on top as though she would have originally had something on her head. I do think the base is a match, why would you have a clear blue base with a white frosted glass figure?
I wonder if she may have been a lamp at one point perhaps? or a candlestick made into a hanging baskety thing?
Or that she was as is, but would have had a matching base and a hanging basket off her metal thingy - but actually I think then she may have easily fallen over?
Perhaps this is one of those times where Sue's aversion to the word 'rare' comes into it's own
