Dairy engine

A "Dairy Engine" steam plant to the John Haining design - it's interesting to see the actual relation in size between stationary steam engines and the boilers used to power them, the boilers always rather bigger than you expect.

A rare model, we've only ever had one in before, that was back in 2011. Commented on that one that the boiler material looked thin, we suspected it was intended for display only. This one appears built in similar fashion, the boiler (and pressure gauge) more cosmetic than functional.
