How can I fix, or get someone to fix, my water globe?

We have a large water (with snow) globe that used to play music when you wound up a circle at its base. It appears that the spring that this circle was attached to is broken. The spring is inside the globe, and there are no screws at the bottom of the globe that can be unscrewed to get inside the globe. Is there any way of fixing this globe? I could not find any make or model on it.
