It was built c1883, Engine No 643. One of only two known to have survived, (the other is at the Henry Ford Museum in America). It does 4 strokes of the piston to 1 revolution of the crankshaft. It is on loan to the Anson Engine Museum from the Techniek Museum Delft. Our sincere thanks to Dr Korving for permission to take the engine to the 1000 Engine Rally, Astle Park.
