Excellent 2 x 2 vertical slide valve engine, Stephenson's reversing gear, marine type flywheel, displacement lubricator, regulator valve, drain cocks. There is a disc coupling supplied for the flywheel - the whole engine appears to have had little or no use and would be eminently suitable for a small full-size steam boat.
Height 15 inches
Flywheel 5 inch diameter
Weight approx 50 pounds
