Woody,
Many thanks, high praise indeed from someone who has seen so much of it! You are quite right, it seems to be called "The Praying Hands". Chris Pye made his for a convent at the request of the Mother Superior.
I must say that I rather like your plasticine mock-up too. The roughness of the moulding with no thought for attempting to emulate the smooth contours of the skin gives it an air of one has lived a life of hard manual labour and who is now praying to their god.
