A pair of C02 gas-powered artificial arms for a child born with a virtual absence of upper limbs due to the effects of the drug thalidomide. Valves are sited over both shoulders and activated by their movements, allowing the elbow joints, wrists and split-hook hands to be moved in a number of ways. This set of arms has a powered right split-hook, with wrist rotation unit and a passive left wrist unit with a powered split-hook. It was made by Steeper in 1964 and issued at the Limb Fitting Centre at Queen Mary's Hospital, Roehampton, London the same year.
