Tiny water cooled stationary engine

This is a small single cylinder stationary engine with a water drum as a cooling system on a trolley. The engine and the company that manufactured it are both fictional. I did take some inspiration from an old Apollo water cooled engine, but the two have very little in common. This engine is much simpler than my previous Hit and Miss engine and my "A" frame engine but can still fit in the palm of your hand. Sadly, there's no moving piston or crank on this one, but there is more exterior detail.
