I believe that this comprises most, if not all, of a set of Clarkson castings for a 5 inch gauge LNER A3. So, if you missed the one I've just sold, here's your chance to knock one up to use next season.
Several large boxes full of stuff, approximately two hundredweight of castings plus some odds and ends, including a jig on which to make the expansion links. All wheels, cylinders and stretchers in iron, there is also a large quantity of gunmetal castings.
Includes a complete set of Don Young A3 drawings.
