This model is based on model 5.30 Vertical Marine Engine from the 1930 set 4-7 manual. It is is more of a demonstration model showing the operating principles of a marine engine and the Stephenson‘s valve gear. This is used to reverse the engine. I built the model using many parts not available over 70 years ago but decided not to fill in cylinder casing with flexible plates as I wanted to retain the feel of the old model. I used narrow strips with plastic five hole spacers between to the connecting rod to give a nice solid feel to them. I also replaced many of the standard width strips with narrow strips. After careful alignment of the crank shaft components, the model will run very well. I find cranks p/n 62 one of least satisfactory of Meccano parts fit a slightly inaccurately made one (lots seem to be) on the most perfect axle and you have problems! Inside the boiler p/n 162 (used to represent the steam condenser) is a Swiss Escap motor mounted on the boiler end. This drives the crank shaft through a connecting chain drive. The picture above is one of the original illustrations from the 1930 manual.
