A "Polly II" to John Clarke's ever-popular design. Easy to fire and drive, they make an ideal beginner's engine - when we lived at the old place the boys had an incredibly tatty little Polly I which used to go bouncing up and down the garden on some portable aluminium track (often ending up ploughing through the grass, up to its flanges in mud) - it never failed to make steam and kept them (and small school friends) amused for hours.
Silver-soldered professionally-built copper boiler, feed by injector and axle pump with hand pump in tender. Slide valve cylinders with Stephenson's valve gear, screw reverser in cab. Mechanical lubricator on left hand running board.
Still in Polly Engineering's current range, the engine remains popular with the garden railway fraternity, not least because of its ability to negotiate ten foot radius curves. There is a large folder of documentation with the engine, including a complete set of drawings, assembly instructions and original boiler test certificate from the manufacturer.
