Stuart "Major" beam engine

A finley made Stuart "Major" beam engine to the design by George Gentry, serialised in "Model Engineer" magazine in 1914 and latterly revised by H.A.Taylor in 1968.

The engine turns freely and runs on air - there's some video of it on our YouTube channel here. Mounted on a wooden base, with pipework for exhaust, cylinder drain and boiler feed pump led out through the back.
