Description
As can be seen here the boiler has been begun and is just as ample as the driving wheels. This boiler was heavily influenced much like the engines valve gear, by the LNER A4 locomotives which currently hold a number of steam speed records. This upsized version of the Gresley A4 boiler has at it's largest OD a diametre of 2120mm.Related content

I know you made the guide and trailing trucks the same for the interchangeability of parts, but it would not be as well balanced.
That may be a concern at high speeds.

The centre of gravity is very close to the centre driving wheel
