Hello Steph,

I'm afraid I can't help with Gwendoline, I don't recognise her at all. An interesting piece though.
I know you're reluctant to upend her, but the way the base is finished can often provide clues to the origin of a piece. Though maybe this won't be necessary, this is such a distinctive item hopefully someone will recognise the maker straight off.
If I had to hazard a guess I'd say she is likely to be contemporary Eastern European, though this is really outside my usual area of knowledge.
Steven
