The displacer  cylinder has provision for water-cooling, the displacer piston is driven by a  Scotch crank arrangement. The output shaft is driven from the crankshaft by a  bevel gear. Bearings are provided by bronze Oilite bushes throughout, including  the displacer rod.\u003c\/p\u003e  \u003cp\u003eThe model was available as a self-assembly kit and could be used in  conjunction with Meccano.
