Long Cecil is a unique one-off gun, designed by George Labram, a United States citizen, and built in the workshops of the De Beers mining company in Kimberley for use by the British during the Siege of Kimberley in the Second Boer War. In 1902, during Cecil Rhodes' funeral procession in Cape Town, his coffin was carried on top of the Long Cecil carriage. Today the gun is located on the stylobate (facing the Free State) of the Honoured Dead Memorial in Kimberley. At some time before 1915 Pratt & Whitney built a model of this gun as a gift to the American Society of Mechanical Engineers.
