Brian Newbound’s

The triple expansion marine engine model designed by O.B. Bolton is one of the iconic designs of model engineering. Despite being a complex model, it has proved to be extremely popular, and nicely finished examples can fetch good prices for second hand model dealers. The original design was revisited by John Bertinat in the mid 80s. Drawings, castings and instructions are readily available from a number of suppliers.

This nice example by Brian Newbound was photographed at the Bristol 2015 exhibition.
