This 19th century wooden hand appears to be an early artificial hand with working grip. Modelled to look like a hand (including fingernails and palm-lines), it moves at the wrist and all the finger-joints are articulated except for the thumb, which bends from the bottom of the thumb instead of the joint. It also has 5 holes in the wrist-plate which presumably took guide-wires for operating the grip.
The Museum doesn't know who made this or who used it - if you know of any similar examples we would love to hear from you.
