'Steeper' heavy-working arm for a right above elbow amputation. Leather socket fitted into a fully automatic elbow locking unit which is controlled by a leather strap, originally attached to appendages which are now missing. The elbow can be locked in six different positions or set to allow free movement. A flexion cord (also missing) should extend from the body appendages and pass through a pulley, sited at axilla level, and then through the metal eyelet on the medial side of the elbow and extended finally to any activated terminal device that has been fitted. The rotary face has three spring-loaded balls which eject the terminal device when the release catch is operated. They also allow the device to be rotated into a number of different positions. The small ball-headed lever on the wrist activates a lock to prevent such rotation. Made by Steeper, c.1946. (Weight: 2.2 lbs 1 kg)
