Willans expansion engine - stock code 5384

An unusual thing to find modelled, a Willans single-acting tandem compound engine. Successfull in full-size, they were much-used in power stations - there are a couple preserved at the Science Museum. This is a nicely made model which runs well.

Height 14 1/2 inches
Flywheel 5 inch diameter
