This is quite a favourite of Stuart Models and many others.
The piston is quite shallow in most double acting steam engines - this is due to the fact that the piston does not need to react any side loads as the conrod is supported in a bearing in the cylinder end cap.
This piston has two cast iron rings in the one groove.
This particular cylinder and pistone combination belong to a Stuart Beam engine.

This pin provides the articulated connection between the conrod and the piston.
Purpose is to improve the sealing performance of the piston and to keep engine oil separate from the combustion chamber.
The piston in an engine has 3 basic functions: Seal the combustion chamber, Transfer force and Conduct heat.
There are many different materials that you can use for pistons and liners, some work better than others.
