Geoff's Stuart Steam engine collection
Sidney Marmaduke Stuart Turner (1869April 1938) After a series of other jobs including an apprenticeship on the Clyde building marine engines, a period at sea and working as an engineer in Jersey (where he installed electricity generating plant), he gained employment in 1897 looking after the steam generating plant at Shiplake Court near Henley-on-Thames, England. In those days mains electricity was rare and therefore most large houses had their own electricity generating plants. It was while working at Shiplake that Turner designed his No.1 Model Steam Engine. He drew up the patterns which he then sent away to be cast. On their return he machined and assembled them and soon showed the finished model at a local exhibition. He then approached Percival Marshall the editor of Model Engineer magazine who wrote an article about the engine. This coverage brought an immediate response and orders for sets of castings flooded in, and a business was established in 1898. The company is still in business and is probably the best known supplier of quality castings for model steam engines. Picture below is from the catalogue for 1906
