Description: | Screw propeller from type-23 frigate, on display in Neptune Court. [The following from memory and TBC: Made of phosphor-bronze alloy, this was manufactured by Stone-Vickers Ltd and is in the Museum partly because it was rejected for service as not exactly meeting the technical design specification.] Josiah Stone established a foundry in Deptford in 1831, of which the non-ferrous works subsequently moved to Charlton in 1917 and became J. Stone and Co (Charlton) Ltd in 1951. Its Marine Department produced the propellers for the 'Queen Mary' , Queen Elizabeth' and RY 'Britannia' among others, and 22,000 propellers for the Navy during WWII. It also made variable pitch propellers and water-tight doors (inc for the 'QE' and RY 'Britannia'). The General Foundries produced specialized alloy castings for industry and aircraft propellers and other parts including for the ' Viscount' and 'Comet'. Stonefoundries still operates at Charlton but mainly for the aircraft industry. As Stone-Vickers the firm has become part of Rolls-Royce. [PvdM]
JM: Conversation with Ron Pawsey, Ken Davis and Alan Reid [ex employees of Stone Vickers at the time this was made] on 24/1/2012, where they state that the likely reason for the rejection was that the blade edges had been engineered too thin when they were ground to shape. Also, this type of propeller was made of Nikalium - nickel, copper, aluminium, manganese, iron - not phospher bronze. Jeremy Michell
