This model is described in Geoff Wright's Book The Meccano Super Models, 1978, under SML 11 and 11A depending which version was constructed.
This is the later K set model of 1937-41 using strip plates in the base unit. The model uses a 1950's Meccano E20R motor. This model was designed for a side plate motor of this type. The K set instructions show a late E6R or an E20B motor.
It features a balanced crankshaft, a valve motion driven from an eccentric on the crankshaft, and a realistic governor.
With careful building the model works well and is an old favourite with the builder.
