Model of a No.8 (below knee) prosthesis made by the late Alex Munro Armstrong of the Queen's Own Cameron Highlanders. He lost his leg, below the knee on 24 April 1918.

Alex Munro Armstrong of the Queen’s Own Cameron Highlanders in the British Army lost his leg below the knee on 24 April 1918. He made this model of a below-the-knee prosthesis for the left leg. It was probably based on his own artificial limb.

Each of the 41,000 British servicemen who lost at least one limb in the First World War was entitled to a free artificial replacement. Initially overwhelmed by the demand, a combination of American manufacturers, new limb-fitting centres, technological advances and the emergence of a valid British limb-making industry eventually solved the problem. However, there were still many thousands of amputees awaiting their first artificial limb by the end of the conflict.
