Chris Wakefield kindly displayed some of his work on the stand at Harrogate. Here are some photos of some of his other handy work.
1). Stuart 7A and Stuart Nr.2 pump.
Not a true depiction of a pumping engine as the 7A is reversible but still makes a good looking model.
2). Large Horizontal single cylinder engine.
This was the one that went down to Harrogate. Two pictures showing the as found condition and the after renovation picture.
3). Twin cylinder mill engine.
The other engine that went to Harrogate alongside a Stuart 10H, showing difference in size.
