A very rare and early model of a triple expansion steam engine. The model is very similar in style and size to the commonly known Bolton steam model commonly made by model engineers. The model features a disk flywheel, 3 cylingers with slide vavles, stephenson's link reverse gear, fluted cylinder head plates, However this model is a lot older in its age and has an antique patina to it. The model has not been tested on steam or air. Any questions please ask. Dimensions: 33cm x 26cm x 15cm.
