Youngs Portable Engine, 1910

This is a Portable Engine, a small steam engine that were used on farms or industrial sites for powering machinery using it's flywheel, much in the same way as Traction Engines were used. The difference between a Traction Engine and a Portable Engine is that a Portable Engine is not self-propelled, and so has to be towed to locations rather than drive itself there. The advantage of a Portable Engine over a Traction Engine is that they were much cheaper. This example from 1910 built by Youngs of Diss, Norfolk can be seen close to where it was made, at the Bressingham Steam Museum near Diss, Norfolk
