This is a vertical twin cylinder (duplex) engine with simple slide valves and Stephenson link reversing motion. It was built by John Stringfellow to propel a balloon to relieve the besieged city of Paris in 1870. The city fell before it could be used. Part of the boiler is seen on the left. The Science Museum store at Wroughton has another Stringfellow engine that was built to propel a balloon.
