The lovely little beam engine, dated around 1840, now in the Bridewell Museum in Norwich comes from the long defunct Bagges Brewery in King's Lynn. It was described in the ME for 5th July 1968 in an article by Geoffrey King entitled 'Model Stationary Steam Engines'. There is a general arrangement drawing, by Mr King, plus a detail drawing of the column.
At least one model was built – in America – to Mr King's detailed drawings. I have seen pictures of the model, but have now lost track of it.
By coincidence, the current edition of Old Glory has an article about the Bridewell with a photograph showing the cylinder cover and valve chest of the engine.
Amazingly its twin sister survives. It is in Jay Leno's museum in America and can be seen in steam at:
