Model Steam Engines

A member brought these model steam engines in to illustrate the development of steam power as used in ships. All of these models actually work, though compressed air is generally used for demonstration purposes rather than steam.

This is a beam engine.

This is a Stuart long engine.

This is a Stuart marine engine

This is a triple expansion engine under construction.

Not much is known about it. It is very old and the builder is unknown. It looks to be a dual double expansion engine. One thing that can be said is that the engine is interesting.
