anatomy and drawing

I've been trying to find out a bit more about votive figurines, but can't find anything that exactly corresponds to "Colin". What is he holding in his right hand, and why doesn't he have any feet? At the moment I don't know what sort of proxy sacrifice he represents – it would be nice to think that he has some healing role, but of course he might be a good luck token, or something totally unpleasant. At least he still has his head. I don't know exactly where he was found, but according to the OS map there's a holy well in the same area – although nominally Christian, a lot of these places are in fact much older. I think I might take a trip out to his (approximate) finding place tomorrow, do some drawing and look around a bit.
