CFA Voysey designed a large range of architectural ironmongery between 1895-1900 which was incorporated in his furniture designs and architectural works.
Originally produced for him by Art Metalwork firms such as Thomas Elsley & W. Bainbridge Reynolds, they were hand finished castings of bronze, brass and steel.
