Bronze Abstract Sculpture - Who is the artist?

Greetings folks!

I picked up this sculpture about ten years ago at a jumble sale in a small village inbetween Leeds and Wetherby. I've never been able to find anything similar so I'm a little bit stumped as to who the artist might be. I mean coming from Leeds / Yorkshire I have all kinds of wild ideas that it might be a maquette model of a Henry Moore or Barbara Hepworth... Then again it might not be!

Its approximately 13" high x 4" x 4". Its incredibly heavy as its made from solid bronze. The casting is quite crude in some places. Anyway have a look and see what you think...
