The Model Engineer beam engine has been a popular model for more than a hundred years. It was first described by George Gentry in 1914.

It was revisited by Exactus in 1959 and that is the version usually built today. The engine is of the centre column type and resembles that of the type of engine made by William Fairburn around 1840 - 1850.

The model is usually to 1:12 scale. Design included some earlier features such as the form of the valve gear with a gab ended eccentric rod enabling disengagement  to make hand starting easier.

This beautifully finished example was shown by Mitch Barnes at a Harrogate exhibition. Photos from the NEWS archive.
