This locomotive Cockerill N° 1930 Suzanne, reproduction on a scale of about 1/20th, is an exceptional piece, unique, entirely made from raw materials, and not a collection of parts of the market, even confidential. It was produced by Mr. Robert Antoine over a period of one and a half years. The director of these machines, who is not a railwayman but an EDF technician, has built about ten locomotives, all different models of course. This gentleman, who disappeared in 2006, probably manufactured this locomotive himself in the 1970s and 1980s, from raw metals or alloys (steel, copper, brass, bronze...). This locomotive is fully functional thanks to the live steam it produces. A section of rail allows the presentation of this locomotive model. A custom made wooden box, supplied, will allow safe transport.
