Swedish myo-electric hand attached to a plastic forearm, with a Münster type 'cup-socket' fitting, for a 4 year old child (with a right congenital below elbow deficiency). There are two gold-plated electrodes and an 'earth' fitted each side of the socket, internally. These electrodes are sited over the 'extensor' and 'flexor' muscles just below the child's epicondyles. The rechargeable battery is fitted into a plastic socket (which is clipped into the child's pocket). Connection to the electrodes is effected by a long cable. Made by Steeper 1978.
